Have this on my mk6 GTI. After going Stage 2 I had a horrible whine when WOT and losing boost. Did some research and found the DV could be the culprit. Got a GFB DV+ and it solved all my problems. Holds boost like a champ! Thanks for the fantastic products GFB!
Seemed more like it was the best edit for a bad situation. The bits and pieces are small, and Bret kept "talking with his hands" while holding them so it looks like it was difficult to get and keep a close enough shot of the components so you could see what he was talking about as he waved them about. Plus the "script" transitioned very quickly between hands on demo segments which are best suited to a close up, and general information that is best served by the medium shot. Not insurmountable problems, but maybe not worth whatever considerations are necessary to re-shoot it with everyone's schedules and such.
Thanks for your explanation Brett. I am using a GFB Respons in my 05 Impreza and it is a work of art. Love your way of approaching problems which happened to yourself. Keep it up!
I have a Peugeot 207GTi, the factory diverter had disintegrated so I replaced it with your GFB DV+, it was quick and easy to install and works perfectly! Cheers.
These are life changing, my car was as flat as the outback and didn't even realise it! Would highly recommend! I've not put my assister spring in yet, but I will when I can get my scan tool.
Installed mine today on my Volkswagen, as the final mod (atleast for this year 😁). Sure. A bit tricky to install. But it works super! Runs with no problems what so ever! Thank you for a good product! Regards from Sweden!
I just ordered a DV+ for my 2014 Volvo S60. I've heard it helps hold boost into the higher RPMs as well. Kind of solving the issue of the car feeling like it falls flat in the high RPM range.
Audi a4 b8 2.0tfsi with an ie stage 2 tune, catless dp, injen cold air and a gfb dv. The car was stock when I got it and now it's so much more fun to drive. Also did the front resonator delete and rear muffler. I bought the car a year ago and just rebuilt it 5,000 miles ago for oil consumption myself. Add these bolt ons and tune after the rebuild. So glad I kept the car and put my time into it. Maybe a intercooler and k04 in the future but I've invested enough at this point. The gfb dv helped hold the extra boost from the tune and dp
Just received a GFB VTA, from Urotuning for my Mk5 GTI. Can't wait for the slightly more spring weather tomorrow, to affix it. Woosh, a feckin' woosh, homeboy! Keep a look out for maybe a DIY, and eventual roadtrip vlogs soon. I've been around the world, but I think I just found my baby! We shall see though. I have a lot more work ahead. The biggest hurdle is learning the docu script writing, techno bs, getting used to all that; skydive into the unknow feeling.
GFB job is awesome! When I turbocharge mais car I certainly will buy some part to support you! Even paying around 100% of it in taxes and shipping to Brazil xD
I installed one on my 2015 USDM Fiesta ST, I couldn't believe how flimsy and shitty the factory DV was! Its guts literally fell apart the moment I touched them with any tools to begin this install. Install was really straightforward, parts are very high quality as well as packaging and associated materials (instructions, etc). It really improved with turbo lag between shifts. I've been reading on some forums though, that some people are experiencing low boost "flutter" type noises. I would assume this is normal, as my stock ST with an open airbox had the same flutter type noise on the stock DV. I'm running a COBB CAI (closed airbox system) and man, is this thing quiet yet aggressive sounding, especially if you opted to install both springs (per included instructions)
Ceazar Carr it doesn't replace it, euro manufacturers use a diverter instead of a BOV because they use an air flow meter instead of a manifold pressure sensor
Ceazar Carr from what I was told and from what I saw on my mk4 jetta, basically the diverter valve is kind of like a blow off valve but like the name says, instead of getting rid of the extra boost it divertes it back into the intake. I might not be right but it would make some sense, to me at least.
Historically I have seen a lot of confusion, misconceptions, misinformation and many questions about waste gates, blow off valves and diverter valves. Hopefully the following helps. The Waste Gate is located in the hot side of the turbocharger and is responsible for setting and regulating the maximum boost pressure. It is a valve that opens and bypasses the hot exhaust gas around the turbocharger turbine and either reintroduces the exhaust gas into the exhaust tubing downstream of the turbocharger or releases it into the atmosphere. The Blow Off Valve (BOV) is located in the pressurized charge air tubing after the turbocharger compressor (cold side) and is for relieving boost pressure helping to mitigate damaging compressor surge when throttle is rapidly lifted or closed. The discharged charge air is usually released into the atmosphere or anywhere in the turbocharger intake tract on vehicles employing Manifold Absolute Pressure (MAP) sensors for engine fuel management strategies. The Diverter Valve (DV) is located in the pressurized charge air tubing after the turbocharger compressor (cold side) and is for relieving boost pressure helping to mitigate damaging compressor surge when throttle is rapidly lifted or closed. The discharged charge air is usually recirculated into the turbocharger intake tubing before the turbocharger inlet and after the Mass Air Flow (MAF) sensor on vehicles employing MAF sensors for engine fuel management strategies. Why recirculate the charge air? To preserve the correct air/fuel ratio (AFR) that has been calculated by the ECU/PCM using air mass measured by the MAF sensor. Releasing that already accounted for air mass into the atmosphere would result in a very fuel rich condition. Waste gate regulates max boost pressure. BOV helps mitigate high volume/pressure compressor surge on MAP applications. DV helps mitigate high volume/pressure compressor surge on MAF applications.
Matt McAlister I think it does matter because when you compress air it's temperature will always rise so you need intercooler to cool it down no matter of outside temperature
Matt McAlister it makes it more effective as the reason an inter cooler is used is to reduse the temperature of the intake air to get more o2 /cm^2 same thing as being lower down (sea level or lower ) you will make more power as the ambient air is more compressed ex (not real numbers) ambient air is at 1 bar flowes through turbo increase in pressure to 1.5 bar now compressing the air adds heat and the turbo adds heat so let's say +10 * c and the inter cooler is designed to compensate for that. so if your ambient is 10 *c lower then where the car was built you could run no intercooler and make the same power or run inter cooled and make more power as the air is more dense leaving the inter cooler. now in the real world it's a lot more complicated then that and long story short you still want to be inter cooled.
Matt McAlister doesn't matter what temperature it is, once the air has gone through a turbo it will be hotter than it was, that's why intercoolers are always a good idea.
Even in cold climates compressed air coming out of the turbocharger is always warmer than ambient (because you have the same amount of energy packed into a smaller space). Intercoolers are just a radiator for the compressed air, moving heat from the compressed air to the cooler ambient atmosphere. This makes the compressed air charge denser, which means you can cram more O2 into the cylinders and burn more fuel = more fun.
ne2i The 1.8t is vacuum actuated so the valve isn't like a on off switch like the mk5. I have the GFB DV+ on my 03 works great as a replacement for the stock Bosch DV
Excellent video! Thanks for that. I'm noticing a very clear decrease in performance after 4000rpm in 208 GT. I expect that engine to go up until at least 5k without loosing torque. I'll replace my diverter with a GFB and see what happens. 😁
I have VTA for Lexus is200... I can't take over anymore because I feel there is lag or surge.. Soon as I push the throttle padel down it takes little time to acclarate.... Before I install the gfb item I installed K&N Airfiter.... HPS intake pipe, HPS Charge pipe and HPS Turbo Resonator Delete... I was taking over so smooth..... But after installing GFB VTA.... It's hard to take over...... If you have the same problem please tell me how to fix it or what I have to do
i know the fiesta st suffers greatly from dumping all the boost pressure during shifts. you get back on it and theres a good quarter to a third of a second before it moves. its so slow 0 to 60 because its losing all that time between shifts, and it takes 2 shifts to 60. if these internals do as you say, thats something that is needed on the fiesta st.
Can you use this with a "Torque Solutions" diverter valve adapter? I believe that piece is only for the sound, does nothing for specs or function, but it would be great to have both. Reply much appreciated!
I have the GFB DV+ in my 1.4T multiair engine, and I am very happy with it. I read some forum posts that say that the forge valve (which is a direct replacement of the stock diverter valve) is better. They say the forge valve has zero leaks, whilst the GFB one, is better than the stock, but still has some minor leaks. Is that true? My opinion is that the forge one is way more complicated to install, with many more prone-to-fail parts. Brett can I please have your comments on this?
I have one of these fitted to my MY11 Polo GTI twincharger. The engine is stock besides the DV+. I haven't dynoed it, but seat of the pants it feels like it holds more boost towards the top of the rev range (above 4000rpm), so I think the factory diverter was bleeding air. The car is DSG so I can't comment on improved throttle response when changing gears.
I have the same concern. Running 18 PSI boost, I close the throttle plate and boost shows 12 PSI briefly with the DV+. That cannot be good on the Turbo. Lots of loading on the bearings. So I went back to stock DV.
Brett, can you make a PCV Bypass kit for the CDNC vag engine please? The "Africa plate" style one? I'm sick of changing the factory one, and getting oil in my intake/turbo 😪
How much did Brett drive his GTI with this improved valve? I'm asking because I know the stock ECU will sense that something is wonky at the turbo (pressure does not respond as expected) and it tries to compensate with the ETB, wrecking it in the long run.
tocsa120ls the kit comes with an assister spring, if you fit the spring it reacts different (priority closed has to snap open) and can bring check light on, If you don't fit the spring (it's optional as stated in the fitting instructions) it acts like a standard valve, I've ran mine for 15,000 miles and 1 year, 0 problems just huge gains.
Any possibility you could make one that would fit on the Pierburg 7.00175.04.0 valve on Vauxhall Vectra VXR? I could send you my torn valve so you could take some measurements.
I have DV+ on my MINI and I have to say, its a lot better than stock. I had a boost leak and I realized it was the diaphragm that was broken. Brett, I was wondering why DV+ doesn't come with any spring stiffness options? That is always confusing to me. I looked at your competitor like Forge and their DV/BOV setup have many springs included for different pressure.
Ch28Kid On mine for the mk4 you can put different Lengths bolts in the top and I believe it is like using Stronger or weaker springs in the forge DV. Like setting pre load but I could be wrong.
Hey would that fit my Opel Imsignia 2.0T? It's the LTG engine and has an electric valve, i guess there are not that many distributors other than Pierburg producing this type of valves.
I've stop using my GFB on my Peugeot 208 GTi simply because it show error after 2 years of using it, in fact it show twice. So I got it clean and reset error code and after some time it appears again. Now I've use back the stock DV. Does GFB needs constant lubricant on the piston?
I'm getting a P2261 code on a stage two plus apr tune after installing the BOV on a 2010 VW MK6 GTI it was professionally installed. what is causing it?
The valve is sticking, it wasn't oiled during install, or the tune expects some amount of boost leakage and the DV+ doesn't do it. A custom tuner should be able to verify and work around this code if needed.
I have the same issue it turned out the inner spring valve remove it inspect it there is some wear put oil or high temp grease there it should solve the issue this code is mechanical stuck code

Have this on my mk6 GTI. After going Stage 2 I had a horrible whine when WOT and losing boost. Did some research and found the DV could be the culprit. Got a GFB DV+ and it solved all my problems. Holds boost like a champ! Thanks for the fantastic products GFB!
I always enjoy how passionate Brett is about this stuff.
I want to find a job like that.
It is a great feeling when you know that something you designed is bringing a lot of people joy. Keep up the most excellent work.
One of the most thorough explanations on RUclips. Great job sir.
Great video as always, but are you trying to hypnotize us or just make us dizzy with those fast close-ups and camera angle changes?
Seemed more like it was the best edit for a bad situation. The bits and pieces are small, and Bret kept "talking with his hands" while holding them so it looks like it was difficult to get and keep a close enough shot of the components so you could see what he was talking about as he waved them about. Plus the "script" transitioned very quickly between hands on demo segments which are best suited to a close up, and general information that is best served by the medium shot.
Not insurmountable problems, but maybe not worth whatever considerations are necessary to re-shoot it with everyone's schedules and such.
Thanks for your explanation Brett. I am using a GFB Respons in my 05 Impreza and it is a work of art. Love your way of approaching problems which happened to yourself. Keep it up!
I have a Peugeot 207GTi, the factory diverter had disintegrated so I replaced it with your GFB DV+, it was quick and easy to install and works perfectly! Cheers.
These are life changing, my car was as flat as the outback and didn't even realise it!
Would highly recommend!
I've not put my assister spring in yet, but I will when I can get my scan tool.
Installed mine today on my Volkswagen, as the final mod (atleast for this year 😁). Sure. A bit tricky to install. But it works super! Runs with no problems what so ever! Thank you for a good product! Regards from Sweden!
does it give a louder blow off sound
I love these tech discussions. Keep em coming!!
I fitted one to my s3 ap and it actually caused compressor surge??!! Was there something I did wrong?🤷♂️🤦 any help would be appreciated.. thanks
Awesome video. Was just looking for information on this the other day. Thank you Brett and MCM!
close up shots move way too much; or use a wider lense or zoom out.
Holy moly this is a powerful little mod! Well done for making it
Just ordered a GFB DV+ for my Sentra Nismo. This vid seems to justify the purchase; great information

Very well thought out piece of kit!
I have one of these and it's worth a mention that they make your car flutter like a beast especially when running an induction kit
Good timing for this video, you may have another customer soon. My 08 GTI keeps throwing codes related to the DV
awesome video explaining this! love it! keep the videos coming!

Got one of these on my Mini, one of the few mods you instantly notice a difference
Great vid, thanks for explaining
Such a genius little device. Gonna put one on my MK5 GT.
The constant changing camera angles made me dizzy.
DV+ GO FAST BRETT Should be Stock on all Turbo cars I love it and Thank you so much for your Design
Quality peace of kit this DV valve, had one on my Mk5 GTI, and i'm about to install one on my Mini JCW.
Great product Brett. I'm getting one tonight for my Mk5 GTi but I still can't decide if I want the one with sound or the quieter one.
I'm doing exactly the same as you tonight, but 4 years down the track... Hopefully, your experience was a good one...
I'm still confused on what a diverter valve does. Does this replace the blow off valve?
Ceazar Carr it doesn't replace it, euro manufacturers use a diverter instead of a BOV because they use an air flow meter instead of a manifold pressure sensor
Patrick Aguilar Cool, I kinda get it, I guess. Thanks

Getting one of these for my mk5 gti!
going to add this in the morning to see if it works on my 2015 turbo fiesta
got the exact valve in my MK5 GTI edition30 and I love it :)
The vid is fine. Great job Brett!
Love this video! use this on my R56 mini
will Brett do anything else apart from valves etc
Not likely, seeing as he works at GoFastBits, who build valves. ^^
can you explain why you need an intercooler. if you live in a cold climate, does it still matter as much?
Matt McAlister I think it does matter because when you compress air it's temperature will always rise so you need intercooler to cool it down no matter of outside temperature

Camera man needs some serious lessons in filming
Would help if brett kept his hands a little more steady when demoing the product. Great product tho. I dont even need one and I'm sold.
Don't listen to them Brett, you're perfect the way you are.
i am not talking about Brett
Craig Tripney I was replying to ratgreens comment about how brett doesn't keep his hands steady.
Ever seen Aussie shows like Rescue Special Ops. In and out and camera shaking seems to be the norm over there. And yes, it's annoying as hell!
Will the GFB valve cure the whistling problem the standard Valve creates? Like an intake whistle
Would it be beneficial to upgrade the valve and also install a spacer? I was looking at this and also the ecs spacer.
Does this upgrade also gives you that sneeze??
Genius. Just got mine in.
Love to have one! But having problem finding it for my Vw Alltrack 2018 1.8 Tsi EA 888 gen 3? I live in Sweden.
Do you have one that will work on the new 2.7t L3B in the Chevy Silverado and Colorado’s?
Does this also make the noise of the air being released or is that just a blow off valve?
need one for the older 1.8T's I like the shuttle valve idea.
ne2i
The 1.8t is vacuum actuated so the valve isn't like a on off switch like the mk5. I have the GFB DV+ on my 03 works great as a replacement for the stock Bosch DV
Great if found it! Thanks for the tip!
I had this exact valve on my Abarth. It improved driveability a ton. The factory valve was exactly like the VW one... plastic garbage.
Butt Beware - I guess yours is not a uk abarth, I was told the uk one is slightly different
Rb5vega Yep, they're different. North America uses the Multiar engine.
Butt Beware.......lucky
Excellent video! Thanks for that. I'm noticing a very clear decrease in performance after 4000rpm in 208 GT. I expect that engine to go up until at least 5k without loosing torque. I'll replace my diverter with a GFB and see what happens. 😁
What happened buddy?
@@bradleywade6471 car exploded
did you do it? got the same car, does it give it a blow off sound?
How about maintanance? How often do you need to grease up the piston with fresh Motoroil? TIA 😀
But what if I don't wanna go fast?
said no one ever......
Buy a Kia
Nice.. Do you have the same concept of diverter valve replacement for 2012 BMW X5 E70 50i N63 Engine? If so, where can I check it out?
I bought one today for my B8 A4 with an APR stage 2. I was getting surge and I am trying to avoid problems down the road.
Did GFB fixed your problem?? Or cause the problem
How do I know which one is for my cars? I looked at the site does not show which valve for which car?
Will this affect passing smog? Now that California rolled out a new software that reads ecu.
May your pistons be hard and your boost pressure make you go faster? :D
I have VTA for Lexus is200...
I can't take over anymore because I feel there is lag or surge..
Soon as I push the throttle padel down it takes little time to acclarate....
Before I install the gfb item I installed K&N Airfiter.... HPS intake pipe, HPS Charge pipe and HPS Turbo Resonator Delete...
I was taking over so smooth.....
But after installing GFB VTA....
It's hard to take over......
If you have the same problem please tell me how to fix it or what I have to do

Why do you zoom in on his hands when he can't keep his hands still for two seconds? I'm getting motion sickness here.
Is the piston held in purely by pressure?
Can a faulty Standard DV throw out a rich condition code ? Vechile Golf 6 Gti. Did order my GFB DV.
Does prolonging the boost pressure, even for such a short period of time, wear our the turbo faster?
KevBounce as long as the compressor blades don’t enter a stall condition, there’s absolutely no effect on reliability.
I have the same concern. Running 18 PSI boost, I close the throttle plate and boost shows 12 PSI briefly with the DV+. That cannot be good on the Turbo. Lots of loading on the bearings. So I went back to stock DV.
Good stuff man
I bought mine and the swoosh plate yesterday. Does it come with i instructions?
Hello MCM TV2 why some spacers have 4 holes and others only 1 please ?
Do i need a tune for the diverter?
bro, a question I have a forge relief valve on my mk6 I would like to know if I can add a spacer to the same valve
@MCM TV2 can this work on a 2009 minicooper country man?
How does it, different than the Forge diverter valve?
Brett, can you make a PCV Bypass kit for the CDNC vag engine please?
The "Africa plate" style one?
I'm sick of changing the factory one, and getting oil in my intake/turbo 😪
Brett talking about euro valve stuff while juggling some random bits and pieces
How much did Brett drive his GTI with this improved valve? I'm asking because I know the stock ECU will sense that something is wonky at the turbo (pressure does not respond as expected) and it tries to compensate with the ETB, wrecking it in the long run.

Can u achieve turbo flutter with the diverter valve?
think the idea is to prevent it
How much boost can this handle? running at around 2.3bar at the moment
This is so cool I want to do this but I still have 4 years of college left before I can.
Brought a Mini Cooper S and my first upgrades are a set of Potenzas and this diverter valve
Would trhese also be found on a TDI and could these be 'fixed' to fill the intercooler faster?
Any possibility you could make one that would fit on the Pierburg 7.00175.04.0 valve on Vauxhall Vectra VXR? I could send you my torn valve so you could take some measurements.
I have DV+ on my MINI and I have to say, its a lot better than stock. I had a boost leak and I realized it was the diaphragm that was broken.

On mine for the mk4 you can put different Lengths bolts in the top and I believe it is like using Stronger or weaker springs in the forge DV. Like setting pre load but I could be wrong.
Hey my diverter balve is stuck how can i buy your product
Will this change the sound of the turbo?
thats an atmospheric blow off valve that dumps to air
legend brett
I have the DV+ from GFB on my 1.8t Mk4. Super quiet but hold the boost well .Not bad price either.
can I get the same PSHHH sound from a DV+ and from a Forge Blow Off Valve?
are oem subaru valves better for a little more boost? thought my donor engine and ecu was stock but its at 17psi and idk much about turbo cars
its a really smart design.
Hey would that fit my Opel Imsignia 2.0T? It's the LTG engine and has an electric valve, i guess there are not that many distributors other than Pierburg producing this type of valves.

daniel loke did u buy the upgraded spring when u fitted the bov spacer mate
but but compressor surge sounds so good!
And murders your bearings so good too!
I'm getting a P2261 code on a stage two plus apr tune after installing the BOV on a 2010 VW MK6 GTI it was professionally installed. what is causing it?
The valve is sticking, it wasn't oiled during install, or the tune expects some amount of boost leakage and the DV+ doesn't do it. A custom tuner should be able to verify and work around this code if needed.
I have the same issue it turned out the inner spring valve remove it inspect it there is some wear put oil or high temp grease there it should solve the issue this code is mechanical stuck code
