I can finally say I have an Integrated Engineering Stage 2 - E85 Audi B9 S4! We performed before and after dyno testing to see if IE's downpipe would make any additional horsepower in my 2018 Audi S4. Integrated Engineering clearly shows on their website that there is no power difference between their Stage 1 and Stage 2 tunes but I wanted to see for myself.

So if you don't have a hybrid turbo don't do down pipes is what I got from this, $1,000+ saved. Thank you
Well you also aren't making as much torque and if you noticed in my video the OEM cat already had some small spots where the cat was melting from the excessive heat that a Stage 1 - E85 tune makes. I'd also consider this upgrade for the health of the vehicle long term.
Great video as always🤙🏻
Thank you
Was wondering when you were going stage 2. But can't wait for the full 9sec car!!
There's only one 9 second B9 S4 in the world that I'm aware of, so that might be difficult, haha
I look forward to these every single Monday morning.
Thank you for watching
I'm jealous of how much more accessible that downpipe is on the S4 than on my RS3. Curious to see if your tires hold that extra torque down low on the street. I think it'll be a big improvement on the track though!
time will certainly tell!
As always great comparison video 👍👍👍
Thank you
Sorry to ask if I missed it but is this on stock injectors and stock fuel pump? If so, will you be upgrading those as well as the hybrid turbo in the future with this S4? I think you did something similar on a S5 sportback. I wonder if the hybrid turbo will move the power curb over to the right more and not feel like you’re losing 40hp up on top in the rpm’s
I shared all of the bolt on parts I was using in the video when I show you under the hood. As for future upgrades, you'll have to wait and see! I do like going fast though 😉
One thing I didn't see mentioned was E %. That can make a big difference. Also what duty cycle/ how close are you to maxing out fuel system? Possible boost is being pulled back some because fuel system is maxed out?
It actually doesn't make a difference. I mentioned in my review video that through my datalogging, dyno testing and performance testing, my car was able to achieve its best results on E63. Nothing was gained at a higher ethanol content. No more power. No more speed. The only thing I ended up doing was taxing the fuel system more. This can be found at 7:37 of this video: ruclips.net/video/Az4z7fb9Wlk/видео.html There is no boost being pulled back because I'm maxing out my fuel system. My hpfp duty cycle doesn't go any higher than roughly 80% on these dyno runs when using this E content %.
@@VancityAudi i guess I can understand that with stock turbo and in that power range. But I've never seen a setup not at least make more low end/midrange power with higher E %, unless the tune is limiting torque through conservative timing and ramping boost in slower to save rods or transmission as a lot of ECU's do this factory. I wouldn't be surprised if an OTS tune did this as well since they have to work on every car its loaded on vs getting a custom dyno tune where it can be matched to the parts installed for most gains.
@@jackweisenburger on this platform it's as simple as it is fueling limited. I've never seen a custom tuned, stock turbo B9 S4/S5/SQ5 perform any better than an OTS tune so I wouldn't be able to comment. What I can say though is with the OTS calibrations having to compensate for blends anywhere between 60-85% ethanol, you can only push it so far. Some people live in extremely cold climates so if they run straight E85 and it's super cold, they'll need way more fuel than someone that is in the heat and running an E60 blend. The necessary upgrade to squeeze more out of the stock turbo would be a HPFP and that is coming to market soon from a couple of the tuners.
Thank you for video bro after this I think only TTE710 can give me what I'm looking for
You're welcome. I hope it gives you exactly that!
Go for the 810!
@@VancityAudi LOL I think I'm gonna wait for you I know you're gonna do it one day
@@bossanac9093 are you surrrrre I am? 🤔🤔🤔
@@davidmusiyenko4158 I don't know about that because I only find out tune end Turbo collaboration it's iE stage3
I own a B9 S4. On the same dyno, I gained 30hp, made a lot more torque far earlier in the rev range when I fitted an I.E Downpipe and moved to 034 stage 2 from stage 1. Both 93 tunes. I run the I.E intercooler and Intake. It also holds on to the power far longer at the top of the Rev range.
Were these dyno runs on the same day? One after another? Same fuel in the tank? And not on a Dynocom dyno? If so I'd love to see these results if you could send them to me via email or a DM on social media.
It appears like I may have made a mistake in something I stated in this video. Apparently this downpipe will not fit a full frame turbo and will only fit hybrid turbos. Thank you to @Sheban for pointing that out to me!
Yes u right only Hybrids But that’s y TTE has made.a new 810 not sure about that yet but TTE-710 is definitely a nice upgrade
@@sandman00ec I'm excited to see what people are able to achieve with that 810!
stupid question, when flashing a new file, isn't it advisable to drive it and let it adapt? and then bring it back on the dyno. Everytime I flash my cars the on-road logs looks quite horrible...after a good few kilometers and few WOT...the logs looks much better.
also, when you dyno your s4 in manual mode, does it automatically shift at redline? reason why i ask because i see it jumps from 4th gear to 5th, then right after 6th gear? are you perhaps chaging gear manually when it auto shifts?
Yes, the car will adapt. That's why we never do just one dyno run. We perform a bare minimum of 3 runs per file to ensure the car has figured itself out. If we see the car is still fluctuating quite a bit we do more runs.
It automatically shifts to 5th when it hits redline. The dyno operator immediately then shifts the gears in the car and that's why you see that happening.
understood. im just really suprised at the small difference the stage 1 e85 vs stage 2 e85 makes.
well, time to put it to the test and see your 1/4 mile times.
thanks for the videos. always nice to watch.
@@Rommellollis as much as I had hoped for a bunch more power I wasn't surprised at all. IE clearly states on their marketing of this product and of their tunes that Stage 1 and Stage 2 tunes make roughly the same power and that a downpipe sees gains once you go with a larger turbo.
I know it's an old video and he's on to Stage 3 & beyond, but for everyone concerned about the mid range power 'loss', keep in mind he is running E85, which IE states is 'close to or beyond the fueling capability of the OEM fuel pump', which they say would be solved by installing an HPFP. So with an HPFP, we should see consistent HP and TQ gains throughout the entire RPM range.
I only ran E65, not E85. The fuel system had plenty of head room. The fact it lost some power in the midrange doesn't make much sense from Stage 1 to Stage 2 seeing as the only part that was changed was the downpipe and the tune is supposed to be pretty much identical except for cancelling the CEL caused by the high-flow performance cat. By running their Stage 2 HPFP tunes you'd make even more torque and one would hope the torque would stay stronger for longer.
@@VancityAudi Thanks for the reply! Sounds about normal for E85 in the US being closer to 65% ethanol on average, seasonally dependent. I'd be interested to see what a stage 2 with HPFP would change on the dyno, I know you're well beyond that deep into stage 3, but maybe it's something I'd be interested in testing myself. Keep up the great content, your videos have helped a lot in building my S5!
@Isaiah I'm not in the States, lol. I'm in Vancouver, Canada. I blended my own ethanol by mixing E100 with our 93 octane pump gas to an E65 blend. I saw optimal performance on the IE tune on E65 and nothing higher. I'm sure with the HPFP installed you'll make more peak torque and hold higher torque for longer. I think that's an excellent idea for you to do a before and after comparison on the same day, on the same fuel and just a tune and HPFP upgrade.
They have a black intercooler don’t they? Would that look better behind a black optics grill?
When I installed mine, they didn't have a black one available.
That's what I'm talking about I have that too i do dont have check engine lights
You won't have a check engine light if you've flashed the Stage 2 software.
How can you go full frame with this DP? ) it has proprietary hot side which isn’t compatible with any full frame.
My apologies if I was wrong in that statement. I was under the impression that you could use this downpipe for the majority of upgraded turbos on this platform.
@@VancityAudi indeed for all the hybrids yes 👍🏻 but full frame, unfortunately, not :(
@@ShebanFPV thanks for the info! I'll make a pinned comment to correct what I said in the video.
have you ever considered switching from IE to 034 since they advertise having a significant gain between stage 1 and 2?
I have not. I don't believe in the claims that 034 has made. As far as I can tell they are the only tuner that I've seen that claims they make more power from a downpipe and going to Stage 2 over Stage 1.
@@VancityAudi 034 has mentioned in a Q&A video that their Stage 1 w/intercooler and intake brings the B9 to 80% of the way power-wise to their Stage 2 w/downpipe and the aforementioned bolt-ons. So the downpipe only adds a small bit. This video is evidence that the downpipe does makes a difference.
@@voop00p and just because they say it makes it evidence? I'll wait till an unbiased 3rd party can prove their claims seeing as none of the other tuners agree with their sentiments. That is unless they've purposefully neutered their Stage 1 tune to make their Stage 2 tune appear more powerful?
@@VancityAudi I just took a look at their respective product pages. While both Stage 2 tunes are distinct from Stage 1 via the downpipe, they have different hardware requirements. 034 lists the intake and intercooler as requirements in addition to the downpipe for Stage 2. IE lists only the intercooler and downpipe as required. For the 034 Stage 1 power graphs I think it's safe to assume no bolt-ons but full bolt-ons for Stage 2 graphs. IE power chart is more ambiguous which bolt-ons are used if any. It's clear they have different approaches to their staging standards. 034 does mention preserving safety protocols a lot so it would make sense if that's why their Stage 1 is more conservative. But from a marketing perspective I can see this approach as a way to make Stage 2 and the required hardware more desirable.
It seems that IE's downpipe is mainly intended for hybrid turbo setups so it's possible that the 034 downpipe is better optimized for the stock turbo. This might be related to why you saw a HP decrease after installing your IE downpipe. Also 034 is way more expensive so maybe it's more performant as well?
@@voop00p Honestly I couldn't tell ya, haha. The one thing I can comment on is that the 034 downpipe is not optimized for a stock turbo more than an IE downpipe is. I'm postiive they are both manufactured to gain the maximum amount of performance period.
Does anyone know if Audi B9 motor is same as Porsche Panamera 4 engine? (2018 971 model)
Same motor as an RS5, not the S4 or S5.
So does this downpipe meet US and Canada emission regulations? Because the power/torque gains are pretty small considering the cost.
No idea if it meets emission standards. We don't have any in BC, Canada that I have to comply with. You'd have to contact IE for that info. For the power/torque gains, as I mentioned in the video this part is not marketed by IE to make power on a stock turbo. It is geared towards making more power with a hybrid or full frame turbo.
Those cats are ginormous. Looks like a DPF on a diesel
"That's a HUGE b$tch!"
Nice
true results I think the DA had something to do with
Awesome again and honest results
The DA and temp definitely affected the overall power accomplished. That's why I did the testing before the install as well so the before and after results were from the same day.
@8:37 what is that boost meter???
Here ya go: ruclips.net/video/jhhMuyeOeE8/видео.html
does the car throw a cel after tuning
Stage 2 software prevents a CEL
iv noticed lower oil temps with a down pipe. i wish i could see my coolant temps🤷♂️
That's what logging is for.
@@VancityAudi I can't find coolant temp in any of the logging software? And it's not displayed on the b9.5 dash. I'm only going off of oil temps.
@darrinscoilsclouds1498 it's probably labeled weird. It's absolutely there though. Sadly my B9 is still a part or I'd try and help
What was the temperature and DA on the previous runs?
I'll have to look it up and get back to you on that.
Found it. On the previous day I was on the dyno the temperature ranged from 58 to 68 degrees and the DA ranged from -47 to 637 DA. MUCH lower than when I did this testing.
@@VancityAudi oh wow, Thats a huge difference! 👍
@@f82sakhirm44 ya, I always try and stress how important it is to do before and after testing on the same day or else people get inflated or deflated results depending on the weather conditions.
Love the videos Adam 💯 quick question though. I have a B9 S4 as well and i dont want to trade her out in the future but i do love the Rs3 . In your eyes with both cars and their gains kinda similar with Bolt ons ( 1/4 ) with the RS3 having the edge , is it practical for me to have both ? Or Enjoy the S4 for now and then trade up for the RS3 maybe even the 8Y?
No need to have both, just get an RS3. I personally LOVE my RS3. My B9 has been badass thus far, but when it comes to pound for pound performance with the same amount of hardware upgrades, the RS3 is WAY faster and more enjoyable to drive.
@@VancityAudi thanks for the quick response man ! And yeah , i agree. The more i think about it . The wife already has a car and i dont need two Audis . Besides that 2.5 is legendary 😤.
performance should be better on the track. one question, is it still on stock high pressure fuel pump?
I went through all of the mods in the video. 😁
@@VancityAudi ohh okay, I was thinking that the b9 needs a high pressure fuel pump for a stage 2 e85
@@ferdi.b93 it certainly does not. IE has done an excellent job of laying out what you need to run each stage. You can find that info on this page: performancebyie.com/collections/ecu-software-tunes/products/ie-audi-3-0t-turbocharged-performance-ecu-tune-fits-2017-2020-b9-s4-s5
@@VancityAudi yea impressed with what they've done
@@ferdi.b93 thank you
Wait what? You you installed a intake, intake elbow, charge pipe, intercooler, and downpipe... went from stage 1 to 2 and only picked up like 10hp and 25ft tq??
Sadly, that's impossible to tell from my testing because when I first went to a Stage 1 E85 tune, the conditions were much better for making power. It was significantly warmer when I was fully upgraded to a FBO Stage 2 E85 setup. The only way to definitively tell that would be do to all of the modifications and tuning on the same day, with the same fuel in the tank.
To be fair. IE removes readiness monitors on the stage 2 file to remove the CEL
Some not all
That's always a part of Stage 2 tunes. Normally in the VAG community Stage 2 = an upgraded downpipe and the companies prevent a CEL.
Thats so strange. I know stage 1 to stage 2 gains can be small sometimes but for this engine its super minimal
The OEM downpipe is so huge and flows so well it doesn't make nearly the difference that it does on other cars.
@@VancityAudidoes this apply for all the other down pipes as well or is there a better downpipe brand that offers better performance?
@andytran-ry7yc on this platform, there is VERY little horsepower to be gained from running any aftermarket downpipe with a stock turbo. It doesn't seem to matter what brand it is.
Thats why i tell my customers downpipes and intakes dont make power
Intakes and downpipes do make power when tuned and on certain platforms.
@@VancityAudi oh yeh? Prove it 😂 would love to see more than 15hp from intake downpipe and intercooler all together
@prestigeteameuroboost done! Before and after dyno testing on a Stage 1 + 93 octane Audi RS6. Literally just an air intake system installed: ruclips.net/video/W35Yk_HQe9o/видео.html
Any drone with this setup? Thanka
In my opinion there is little to none.
@@VancityAudi thanks! Still pretty quiet in comfort?
@@corycooper4955 ya, it's still awesome to cruise with.
@@VancityAudi thanks!
Odd. What is the selling point for the Stage 2 if it provides no power? Is it just to clear any CEL from modifications, or what? Never heard of a stage 2 that provides nothing.
Even on stage 1, full E85 is already maxing out fueling so you’re right, there really is no point. On straight 91/93 or E blend, stage 1 is not fuel limited, so jumping to stage 2 does produce gains.
Looks like it is to remove the CEL as well as to provide more torque as shown in the video.
Would love to see a video on sound after the downpipe install.
Already filmed and coming to the channel soon!
@@VancityAudi awesome, I just subbed today!
@@voop00p thank you very much!
I never used e85. But i had stage 1 034 93 with intake and intercooler. I drove a while with that setup and then catless with stage 2. 034 says like 10hp difference if you already have intake and intercooler but in practise my car is now 1 fully second faster from 100 to 200 thats a big gain i think.
So i think with a colder day etc. You will be much faster i think
Nice! Happy for the gains you saw. We'll see how my car responds on the street and track rather than a dyno.
@@VancityAudi i think you make gains. Another thing i managed was EGT. I cant see how hot it is but with the catless i can make more pulls and runs before the car holds back.
@@zuiddijk what intercooler do you have? Intake air temps have a lot to do with timing pull.
@@VancityAudi its from HGmotorsport HF series same like wagner.
When are you gonna go tte 😬😬😬
🤔🤔🤔🤔🤔🤔
Still using osmo gimbal
I haven't used an Osmo gimbal in years
U went with high flow in stock turbo that’s why u lost power u need more air for that high flow buddy
Tuners other than IE claim that even a stock turbo will gain power with an upgraded downpipe. They would all disagree with you.
Wanna gain 50k more subs? Switch to mph
I agree that I need to remember to do that on the dyno and the drag strip.
Good to know there's absolutely no reason to install a downpipe unless you're going stage 3.
Well, it does improve the sound and unlock some additional torque. If you're only looking for horsepower though, don't bother.
