Audi B9 S4, S5& SQ5 Staged Build Guide

[@sujitroutray1]

I bought all of it today. All of it. Waiting for all to get delivered. Thanks for the video, mate.

[@Vaguh]

Hope you enjoy it!

[@ndsb2001]

Super helpful as always. Got a 2018 Audi S4 and had headed down the APR path, but you opened my eyes to IE. Been super happy so far after a few mods.

[@salninethousand2496]

B9.5 SQ5 here, and in the Seattle area too. I just went down the APR stage 1 path and it has not gone well. Tune is a bit wonky (notable surging) and the intercooler install was a disaster (poor directions, bad brackets, ill-fitting parts). In the midst of trying to remedy both issues so I won't throw APR completely under the bus yet. I'm just shocked the experience thus far given the size and popularity of APR.

[@BeardedBruv]

Awesome video, love seeing the progression and also excited for all the future vids and installs! Once IE starts pumping out that SQ5 hardware I’ll be a happy man

[@RollTideGaming]

This build is so sick. I have similar engine mods but different brands. I have: - Unitronic Carbon Fiber Intake - APR intercooler - CTS Downpipe - CTS inlet pipe - Forge Motorsport Blowoff Valve - Custom Tune from local company (RaceMod) - Purchased AWE Track exhaust (from down-pipe back) with 102 mm tips Install on exhaust in 4 weeks and I can’t wait!

[@gussferreyra5631]

Yes on the downpipe 101! Thanks for all your content!

[@joesforspeed]

Very interested in the downpipe video and the fuel it install.

[@1Kurgan1]

Great video, but I was wondering where is that final graphic or the links in the description? I do see the link to IE, but not to specific parts.

[@Vaguh]

Check out the mod list page on our web site. Most links are there. VAGUH.com

[@annenominous7220]

how do you pass emissions with these mods? I can see stage one passing emissions, but after that, I don't think I can run that in Maryland... any ideas?

[@Vaguh]

Check out APR. They have emissions compliant mods. I just installed their stage 3 Turbo.

[@strudel4441]

034 is the way for this motor.

[@syafiqrasyid5918]

Stage 3 need 4bar map sensor?

[@RealEstateJackOfAllTrades]

Just did turbo inlet, cold air intake, and 034 stage 1. I’ve noticed my car will smell pretty hot if I am going out and driving it hard. So sounds like a need to jump on upgrading intercooler asap then, huh? And you said you felt like it gave you good amount more power?

[@Vaguh]

The intercooler helps with temps a lot, the extra power I felt was from the cooler intake temps and higher flow. It’s especially noticeable at the track on a road course.

[@z28camarobc]

so in general, what's the total cost for stage 1? stage 2? and stage 3? parts only

[@coppinques7863]

stage one with ie upgrades is around 2k. going the cheap route i would say around $600. stage 2 with ie is probably $1500, cheap route 800. stage three would be around 5k.

[@darrinscoilsclouds1498]

im about to install a tte810 and hear lots of horror stories when running ethinol. how often if at all do you run ethinol and how do you stay safe?

[@Vaguh]

@@darrinscoilsclouds1498 I run ethanol about maybe 6 or 7 times a year. Mostly when at the track or making vids.

[@annenominous7220]

can't yo ubuy parts from audi racing for these cars, my german friend says he does for his a6.

[@jeromemoorer1299]

what made you decide to go from 034 to IE? I currently have a stage 2 034 tune on my 19 S5 vs the APR one that was on it when I purchased the car. Loving it, but wanted to get your thoughts.

[@MrSiobert]

I just ordered my midpipe for my 2022 S5. When did you plan on doing a video? I’m excited to see how it sounds

[@Vaguh]

I’m going to try to get it done later this week.

[@MrSiobert]

@@Vaguh thanks man! Keep up the good videos

[@gregrogers3998]

Yes please on the DP video. I am in CA. B9 SQ5. 034 E85 Stage 1 ECU stage @ TCU, intake, turbo inlet, intercooler. Stock exhaust. No DP yet.. is it "REALLY" worth it (I would go with high flow, not empty DP)

[@davidhays9531]

Great video. Would a ie stage 2tcu work with another stage 1+ecu tronics tune?

[@Vaguh]

Yes it will, but they are optimized when working together. That being said I know of a few who are running different ECU and TCU tunes without issues.

[@allenz4772]

You said the new TTE810 will make 100hp more than a TTE710. Did TTE say that or it's your guess? I couldn't find any differences between TTE810 and TTE710 on their site, even descriptions are the same.

[@Vaguh]

Yeah, I’ll see if I can find the link after work. When The Turbo Engineers first announced it, there was a blog post somewhere. The main difference is the 810 has less back pressure, and more fins on one of the blades. They estimated another 100 HP possible over the 710.

[@abzdadon74]

To go to stage 2 we don't need a intercooler? I currently have a ecu and tcu tune and really want a downpipe Purley for sound but not sure if a intercooler is absolutely necessary

[@Vaguh]

Technically you can do stage without and intercooler, but I would recommend it as stage .5 . Stage 2 will have things running slightly hotter. An intercooler will help keep your temps down and power up during any spirited driving.

[@CoachD4]

Shit, I'd be getting an intercooler and a vent temp mount. 2 pulls in summer weather and dadmobile will be saying *aha no stop*

[@Shulcyo]

Can anyone recommend good rear diffusor for B9 SQ5? I am really hating fake exhaust pipes on my car and want to replace it

[@aaronbrown6266]

Have you had or heard of any fuel injector problems or failures with any of these tunes? My local shop spoke about 3 B9s that had injector failures which resulted in piston ring damage. Consequentially, roasting the engine. Made me a little bit nervous. However, I am going forward with an IE stage 1 ECU and stage 2 TCU. I eventually intend on adding an IE CAI and intercooler. Maybe more down the road? Excited to see how my '18 S5 responds to more ponies and torque!

[@Vaguh]

I haven’t heard of any engines getting torched, but have seen one person with injector issues. Although, that happened prior to him tuning. Also, I haven’t had any issues with mine. Some people have been switching plugs, but I e stuck with OEM and haven’t had any issues through 25 k miles with all the testing and tuning.

[@aaronbrown6266]

@@Vaguh Thank you for the reply! That gives me some more confidence. I appreciate it and I love your videos.

[@davidmusiyenko4158]

I’m a little discouraged about the lack of support for the B9 SQ5. but can’t wait for everything to come for it.

[@Vaguh]

I hear ya. It’s coming, we should have videos for those too.

[@salninethousand2496]

Same. Have a 2021 SQ5 and seems nobody, esp. APR, has an ECU tune for it. The vehicles been out on the street for almost two years now. The tuners keep saying the 2021 MY has a completely different ECU than 2018-2020. Very disappointed all said.

[@davidmusiyenko4158]

@@salninethousand2496 I have APR on my SQ7 and it’s awesome. Had them as the first tune on my S5, it’s a good tune.

[@warwick724]

Wondering if having the heat shield and the stupid plastic cover for the engine removed helped with anything temp related ??? Waay more modded then my RS5 .. just wondering if it was taking off for the vid or always off ?!?!

[@Vaguh]

Nah. I had a Funk Motorsport turbo blanket on with the TTE710. Back to running it normally with the engine cover back on my TTE810

[@bk_quattro]

Awesome video man 👊 would love to see some parts to start getting developed for the c8 a6. Needed a bit more space so went with the a6 Allroad. The performance upgrades are just so limited at this point.

[@darrinscoilsclouds1498]

im thinking of swiching tuning company from IE to 034. what would you run if it were your money? iv got a b9.5 s4

[@Vaguh]

Knowing what I know now, if it were my money, I’d stick with the one I started with. There’s not a huge noticeable difference between the two unless you’re really pushing it at the track, and even then they drive really similar. 034 TCU shifts really hard and aggressive and IE is more aggressive on launch. What stage software are you running?

[@darrinscoilsclouds1498]

@@Vaguh stage i ecu and stage 2 tcu. but I've bought every upgrade, except injectors, and a hybrid turbo. I just have to install everything. so I'm gonna be upgrading to stage two tcu soon

[@RaNm2418]

Hey man! I just bought a ‘21 S5 Sportback.. I wanted to go IE intake with turbo inlet pipe, IE stage 1 tune on 93 and an intercooler. I want to leave the stock exhaust. Does that build make sense?

[@Vaguh]

That build is a great choice!! Use code itspronouncedVAGUH at checkout at IE to save about 5%.

[@RaNm2418]

@@Vaguh Thanks! Appreciate the feedback and will definitely use the code.

[@thewillyagami123]

How secure are those fuel lines? Notice the are outside of the ring

[@Vaguh]

They’re good. The rings are for the quick connect fittings, which I do plan to put on before I hit the track. The hose wouldn’t go over that ring.

[@00gtp]

I wanted a little more sound out of the 2022 s5 I just got, was a little disappointed with the stock sound, in dynamic it definitely has some burbles and if you try to make it happen you get some pops. I just bought the vps mid pipes from ecs and waiting for them to come in. Since you haven’t posted a new vid yet and probably have them on your car by now, did I make a mistake jumping the gun on the vps pipes? I didn’t know ie was also working on these?

[@HerpidyDerpDerpidy]

Do you run any e blends? I also live in WA and am looking to run e40 IE tune but am unsure where to source fuels to mix with 91.

[@Vaguh]

Yes, in fact, I’m going to go get some in the next few days. There’s a Gateway Chevron in Snoqualmie that has e85 and a place in Marysville, I think.

[@yaheard8335]

Do you know an about of what kind of power this stage 3 setup is making

[@Vaguh]

In the neighborhood of 700 hp, depending on you fuel with a hpfp.

[@ThesGt]

i saw you have APR ignitions coils, does that makes any difference on any stage? are the stock ignition coils good or we should swap them with something else?

[@dudesquotemovies]

Did IE figure out the stock fueling issue? I saw they released the stage 3 tune, but no mention on their website about needing a high pressure fuel pump. I Have a 2018 S4 and I’m trying to figure out what direction to go when it comes to tuning it. Keep up the great content

[@camfiorini]

When will you post a 034 E85 1/4 mile time?

[@Vaguh]

Likely this summer when I go back to the stock turbo and do stage 2 testing. It wasn’t available until after I put the hybrid turbo on. I’m pretty excited to see how it runs.

[@camfiorini]

@@Vaguh Got it, I have the Stage 2 tune just scared to do the e85. Worried about the warranty and if the pumps can keep up

[@Vaguh]

@@camfiorini you should be fine. They pulled back the power to maintain safe operation for the hpfp. Only be concerned if you’re doing it in low DA. Like sub -800.

[@Vaguh]

@@camfiorini also, the most you will likely see happen is fuel cut from the hpfp if it can’t keep up. I’m confident, that 034 backed the tune off enough to keep that from happening.

[@camfiorini]

@@Vaguh Ok thanks for the info - I'm gonna switch on my next tank and get some vbox data

[@ThesGt]

Hey man, did you moved away from 034 to IE ? I remember you had 034 for this same platform before, any reasons on the change?

[@Vaguh]

I’ve been testing a bunch of tunes and hardy for the car. Currently on stage 3 running IE and 034. Check out my latest dyno video.

[@trentimus5700]

Man, I know you said you’re not “sponsored” but about half way in and this sure does feel like an ad lol

[@Vaguh]

Fair enough. This video definitely has that feel. I just have all the IE parts on my car right now, likely will for a few more months. The truth is, they did send me all these parts for reviews and the see how fast we can go, in exchange for some videos, so some of these videos will be IE focused. One thing I’ve noticed, is that not all the tuning companies have prioritized the same mods for this platform and many of them are just coming out now. 034 has a bunch of suspension stuff, but just now rolling out inlets, while other companies are stopping dev at stage 1. With all the variety in the tuning companies offerings, it’s tough to have just one companies parts on your car. Appreciate your feedback, feel free to drop ideas here for upcoming videos.

[@jonathanrentfrow]

@@Vaguh For a video that starts with "Not sure what parts to buy?" Feel like a disclosure at the begining is fair as a bulk of your videos are comparison focused. I'm happy to see the S5 is sponsered, just feel like some transparency would be appriciated. Legit rolled my eyes through half of this video. Regardless, definitely value your opinion. Look forward to more install videos.

[@Vaguh]

@@jonathanrentfrow thanks, I thought I covered that in the video (11:59), but you’re right, first thing would have been better. The car isn’t really sponsored, we’ll be swapping parts back later this year, and you’ll still get honest feedback as I install and use them.

[@trentimus5700]

@@Vaguh thanks for the reply. First I want to say, I don’t think you’re a disingenuous person. I do think that IE is playing loose with the rules of making this an advertised partnership. You don’t strike me as the person that would favorably review something just because you were given it or given a major discount. That said, I do think this is an advertisement at the end of the day. For your benefit, for Integrated Engineering’s benefit, and for us as viewers to continue to trust your well thought videos it should be distinguished as such. You start by thanking IE and talk about partnering with them, but I think this could all be avoided by saying “thank you integrated engineering who has partnered with us and are providing free/discounted equipment to prove what this platform is capable of” You do talk about it mid video, but leading with it keeps us all as your fans/viewers from rolling our eyes by the time you’re basically pitching the 3rd IE product. I can tell IE makes a solid product, but it shouldn’t discount their products at all if you make everyone clearly aware that they’re just sending you $$$$ of free items. Thanks for being open to feedback, and again it doesn’t discount that I do like your videos. Just felt like I was watching an extended ad via a content creator as we see now so often with social media these days.

[@Vaguh]

@@trentimus5700 awesome feedback, and thank you. Those are great points and I’ll keep them in mind for future videos. Shoot me a DM on another platform and I’ll get you some swag!

[@petarkiteski4502]

What are your thoughts on integrated engineering vs 034 motorsports? How do the tunes differ in your opinion?

[@Vaguh]

So, I have to say that I haven’t driven the current revision of the 034 stage 2 tune. I went to stage 3 and started beta testing before it came out. I do plan to go back and do a comparison of all the stage 2 tunes once I complete the stage 3 video series that kicks off tomorrow. Prior to that they were both great to drive. I didn’t have the same experience as some others on the launch with 034. IE launched harder. Drivability between the two was really similar with IE having additional crackles. 034 has since added those. Here’s a bunch of data from my track times for all the stage 1 1/4 runs. Check it out on a computer. www.vaguh.com/blog/cyf695nfxbvuqliof9kis2lfmyj8hd

[@petarkiteski4502]

@@Vaguh I appreciate the response! Which one do you think FELT more aggressive? Keep doing what you’re doing man can’t wait for the future videos!

[@Vaguh]

@@petarkiteski4502 at the time, IE. It launches harder and crackled. Their throttle mapping seemed a little more aggressive as well. 034 got the tuner from APR for their last revisions and I think their tune drives more aggressively now, though. I’m looking forward to seeing what it’s like.
