We dragy tested the stock Alfa Romeo Giulia 2.0l and then added the JB4 piggyback followed by the TMC Motorsport piggyback.
We obtained 1/8 mile dragy times and trap speeds as well as 1/4 mile times and trap speeds and also 40-100mph times for each.
Thanks for doing this man. Helped with my jb4 decision.
Awesome! Hope you're enjoying it.
Would love to see a well documented test like this with the jb4 vs Squadra tuning. Obviously different tunes but would still be interesting
Agree.
@@bhvrdr I saw a review by fast4lfa and honestly thought it was horrible. The whole video sounded like a bad sales ad talking about how it “feels better” or “just makes me want to drive my car” or it’s more “drivable”. I need data. I’m trying to decide between the two right now.
@@yendor86 yeah i prefer numbers and datalogs of what the car is doing. That said we have alot of data now that the tunes are similar in power. Check here...

The effort of this video is amazing. Subbed.
Thanks so much man. Ill get better. Im working on it.
Thank you for the extensive testing on the TMC. I was under the assumption that prior to remapping power, it gave ability to remap the gearbox itself ? I'm more interested into shifting gears faster / maximum responsiveness without changing stock power levels. Were you able to test that ?
Thanks for the comment. The gearbox cannot be modified without a flash tune of the tcu or transmission control unit and none exists for this platform. There are some sleezy products that claim to plug into your obd port and change transmission behavior but they are snake oil. You can do the same adaptation reset unplugging the battery overnight
There is a tcu tune for this transmission.
What an awesome video!
Thanks man!
Very helpful. Thank you.
By any chance have you ever tried the RaceChip GTS? I picked one up used and it definitely adds power, but same as the TMC it throws codes when I put it in the most aggressive setting. Waiting on a dragy but until then I’ve been using an OBD measured 0-60 and it seems to have made a noticeable difference. Will look for flat safe areas to get a 1/8 trap or a 1/4 trap speed soon
Nice comparison! But how did you activate dragy 40-100 mode? That’s so practical! I almost never have space for 60-130 runs and I can’t find 40-100 mode anywhere in the app.....
Thanks for the comment. Great point. On dragy you can setup custom definitions. Go to the "GO" page in dragy and click on the "+" symbol to set custom definitions.
@@bhvrdr wow thank you so much! Will definitely try it! BTW I just got a 18 S5 coupe and got 4.2 0-60 bone stock, I was pretty surprised! Regardless I’m going to JB4 map3 soon, do you know what kind of 0-60 and 1/4 I will get? I watched all your S5 videos and only see map5 runs so...
@@justinswift5745 map 3 is going to be very close to map 5 anyways. I wouldn't be surprised if you're in the 3.8 sec range. Probably 12.0 ish quarter mile around 112-114mph. Great car.
@@bhvrdr Oh really? I have never experienced sub 4.0 0-60 before 😂
anyway even in stock form this car is already pulling very strong on the low end, but definitely lacking a bit on the top end coming from a 16 Camaro SS, but a 12.0 quarter mile seems will make it pull as strong as the SS on the top end and put it in another league on the low end! Thanks man!
I have a JB4 on my Alfa Romeo and my service electronic throttle control came on my dashboard, how do I get rid of that? How did you get rid of yours? You didn’t quite explain how to get rid of it in this video.
Use map 1 and you want to pull the code to see what caused the electronc tb code. Literally dozens of things can cause it from low battery voltage to using a gfb diverter valve. If its just running too aggressive of a map you can reset it cycling the ignition
Hy just purchased a 2023 estrema giulia i would like to put a jb4 can you tell me if you had any problem with it since .
I’m on the brink of purchasing would you say JB4 is the best and fastest tune route to go?
Yes pretty much. Its logging and gauges and ability to switch maps paired with it being undetectable once removed paired with it giving at least as good of gains as any flash tune make it hard to beat. Plus you can sell it for $450 when you sell the car making it basically free if you buy it used yourself lol
What this shows is leave it stock
Great video. But I'd stick with the stock tune. The tiny bit of extra performance isn't worth the hassle.
The hassle is very little and the extra performance is more than a tiny bit, it's night and day really.
@@TheAnon11 Going from a 13.5 1/4 mile to a 13.3 1/4 mile isn't worth voiding the warranty. Sorry.
@@realestateeric JB4 won't void warranty, it's a piggyback. It alters signals to sensors to make the car think it's hitting lower boost targets than it is so the PCM compensates, hence higher actual boost levels. My Jeep Wrangler has the same engine, I went from running a 14.5 bone stock to a 13.5 after bolt ons, methanol injection and JB4. I picked up an 8-10mph increase in trap speed. This is all on 94 octane pump gas too. Stock they make about 230-235whp. My Jeep put down 333whp on a roller dyno. Thats 100whp gain. I also dyno'd it without the meth and switched to another custom map I made for no meth and it still put down 315whp. So intake, exhaust, some premium fuel and a custom map 6 on JB4 and I picked up 85whp.
@@TheAnon11 sure can't tell it by the times 2 tenths for how much money and time?
what the hell is up with the fault for TMC?
The map is just a bit too aggressive.
Nice upload! Maybe add a little fuel as you do the testing to make it fairer?
Yeah its a good idea. Thanks
Is the JB4 on map1 or map2?
Map2
what are the 0-60 mph runs i want to know those aswell
This was testing to asses the cars power output. 0-60 is traction limited in this rwd car so would tell us nothing relevant. Theyd be all over based on launch only.
@@bhvrdr the eurocolpoltion tune i heard allows you to take off traction control in d mode. and it also allows you to take off limeter for top speed
@@Shortyzworldtv top speed limiter is removed with ec. They dont disable esc or tc but give you a "sport" version thats supposed to be less intrusive but people who actually track the car report its very inconsistent in how it intervenes. Id still do the race mod to fully defeat it if tracking
Hey how did you fix the error code?
I worked with them to reduce the map offset but i don't believe they ever changed them for production so id just ditch it
@bhvrdr to clear the code, did you do the basic code clearing technique - on+ off and steering wheel turning? I'm using Madness and was told dynamic+race mode on a pedal will cause errors. (While using their piggyback)
@@RP-pg8yx it has nothing to do with race mode or dynamic. Its their map. They need to fix it. I clear it with jb4 but you can use the accessory on,/off technique as well and as long as you have the mpp off the code will stay cleared.
@bhvrdr Thank you! I'll try to find a better piggyback eventually.
To slow not worth the price i we be buying the madness auto works piggy back
Madness is the same as tmc. Identical. Jb4 actually has the world record highest trap speed, 40-100, and 60-130 for any stock turbo giulia
That Quad badge needs to go lol
Many folks aren't aware of the historical significance. It has been used for 90 years to bring good luck to alfa drivers in racing...of which i could always use ;)
@@bhvrdr Its commonly known as "upbadging" which I agree, is a faux pas considering its usage in he modern era.
@@Toxie2725 the quadrifoglio badge has been used for 100 years in racing. The giulia quadrifoglio has been out for 4 years ;). Never seen a giulia quadrifoglio with a badge on the trunk. Ive seen the alfa track cars with it though
@@bhvrdr After World War II the quadrifoglio was used to distinguish particularly sporty versions of production Alfa Romeos, appearing for the first time on the side of the Giulia TI Super of 1963, also called Giulia Quadrifoglio. This was a variant of the Giulia sedan devised for competition but regularly put on sale; it had green four-leaf clovers on its front wings, without the triangle.
Just pointing out that to many, it makes it look like you're trying to make yours look like a QV.
Yup it's also been used for a hundred years by alfista for luck. We put it on the hood or trunk for that. Both purposes. If someone thought one 9n the trunk was upbadging they don't know the brand heritage since none are badged that way from factory.
Geez, no quicker than my stock old 2004 SRT4 Neon/Skittle or the next one after that, a stock 2010 Cobalt SS/TC.
Yeah but then you had to drive a neon and a cobalt. Punishment for something?
Just to point out, Dragy isn't SUPER accurate with MPH readings. Need to be doing this at the track for the most accurate results.
Dragy is ridiculously accurate with mph to .5 mph. I have hundreds of runs on it at the track on everything from fwd to rwd to awd cars.
ruclips.net/video/A4xsy2fGy8Q/видео.html
Draggy is extremely accurate.shouldnt he a talking point as it's been out for years now.my track slips match my draggy down to the thousandth and mph is dead on every time when signal is available in the testing areas or at track
Just test drive it. Worst car ever
That's what sells them. Test drives. Theres not a single sedan out there with a faster steering ratio (quick turn in), carbon fiber driveshaft, nble handling and the 4 cyl model does 0-60 in under 5 seconds bone stock.
@@bhvrdr went to test drive one, initially not really wanting to entertain the idea of buying a 4 door. It’s being delivered to my house this Friday lmao
@@Printedperformance lol, yeah that happened to me too. Congratulations!
@@bhvrdr thanks! Absolutely loving the car. Just finished the race mode mod and adaptive suspension module update. Go pedal and jb4 are on their way after the holidays… then the hybrid turbo after some other tidbits lol.
Would love to see you get a pro tune and then see the times on draggy
Yeah unfortunately the guys whi had dyno tunes with their hybrids were a bit slower. They ran into torque limiters and multiair limited their ability to run high timing. Maybe some day someone will figure out how to get real timing advance on these multiair
Really bro? It takes a tool, Alientech, Dimsport, Autoflash or chinese copy. And custom table definitions, ie custom tune.
Is this stock time for a veloce or base model. Since the increase is small i think veloce?
Correct. 280hp veloce
Great video, bought a jb4 and this was a good selling point. Question, why did the density altitude change?
Thanks. Weather changed slightly over the hour. Very slight.
Look at the outside temperature gauge, you'll see the temp drop from 85 to 82 degrees at one point.
