Who bought their RS5 to modify...

[Bullhorn717]

APR tune is starting to sound more and more tempting. How much max boost are these cars making stock and how much boost increase does stage 1 see? I’d imagine not many RS5 owners have one of those P3 gauges or manual boost pods to read real boost pressure.

Just be careful, while APR does give a limited powertrain warranty if you purchase the "plus" program, it is not complete. Audi will cover literally nothing on the car if they discover it's tuned. Guys on here will be quick to jump in with magnuson moss act etc, but the fight is real. So just be ready to waste your life arguing with Audi should you need any repairs at all, even if they aren't related to the drive train.

I bought the RS car so I didn't have to noodle around with warranty and tunes, when the warranty expires all bets are off though. Tunes always make the car more fun 100%. The APR plus tunes are typically heralded as "the way the car should come from the factory" I can attest to this on my APR Plus tuned Golf R.

JB4 is great. You know exactly how much more boost it’s adding at each map. Very smooth and easy to go back to stock. Hardest part is the cable thru the firewall, but not too bad once you figure out how to do it.

That would probably be the route I take if I do decide to do something. I use the dealer service for most everything while under warranty and would hate to go else where to avoid getting flagged. Does the JB4 also address the tip in and mid range torque that the APR tune owners seem to mention as a big benefit?

I can’t compare to APR. I’m running map 3 which is 4 psi over stock. It feels very much like stock drivability to me just with more power when you hammer it. I may try E30 mix and map 4 when weather warms up. I was not sure of piggy backs before, but it’s really an excellent product. You can also make back 75% of the cost when you sell it. Big plus is it supports turbo upgrades down the road.

I used to really be into modding all my cars but nowadays, I'd rather have "pretty dang good from the factory" performance/GT car and then lightly dabble around the edges (mostly minor aesthetic things). Modern performance/GT cars (RS/AMG/M/etc.) have raised the bar enough to make me happy as is. With the B9 RS5, besides tint and an outside possibility of a set of wheels, I'm very satisfied with it. Plus I'm over having to jump through the various hoops to work out modding issues, having to revert the car back to stock parts/components when needed (dealer visit, inspection/smog, warranty), etc. I'm more interested now in how to improve longevity/preventive care, maintain factory level performance, etc. especially with German cars (fingers crossed, knock on wood).

This is where I am at too. Besides all the gremlins that arise with knocks, squeeks, and buzzing from lowering, tuning, exhausts, BBK's, etc.... its also the cash consumption. This is not a cheap hobby, and these are not cheap cars. Id rather buy another car than spend $20k tuning mine to some arbitrary version of perfection. It is tremendously satisfying to get your car "perfect", but like renovating a house, I only want to do it a few times before it becomes tedious.....

Not knocking it by any means, it is a form of expression, a hobby, and a passion for many and I enjoy watching other people do amazing things with their cars now.

I have a 2014 S4 that's modified and its my daily. I always felt it lacked power compared to AMG and BMW M's. I did all the mods after warranty on my S4, but the stock parts had issues with the extra engine heat and wear and tear after 45K miles:(

I bought an RS in late 2018 and it was incredible off the dig but lacking in mid to top end. I go to car meets all the time and hang out with car guys. I wanted to build my RS5 while all components were fresh and strong. Not like my S4, water pump, PCV, Hydraulic motor mounts, valve cover gaskets, lower control arm bushings needing replacing due to wear and tear and engine heat!

So I went Stage 3 with upgraded Turbosystems Hybrid turbos. No regrets, It is a Beast off the dig and a freeway Beast as well. I don't track it as it is a GT, Heavy and Heavy. It doesn't handle as nimbly as the S4 but it is a GT! I get it but I like response. For the price and the mods it is the best bang for the buck. A really nice, really fast, really comfortable and very quick GT.

It is my weekend car and I don't have enough money to buy a more expensive car and I am happy with my build. It needs an Intercooler and better suspension. It's too heavy to drive in a spirited manner. Too much body roll. I'll wait until I save up. The Intercooler and High pressure fuel pump upgrade are next.

No ETA as usual, like the carbon intake, like the turbo inlets, like a Stage 2...

sorry to hijack, but just reading about the tuning options.

Isn't the Macan GTS utilizing the same 2.9T as the RS5? So likely same ECU? That would be ground breaking for the RS5 for power.
https://www.cobbtuning.com/2020-pors...-gts-pdk-wm-s/

I keep flip flopping on what to do next. I loved my B8 S4, and I loved it - the Golf R is fun to drive around, BUT....I miss my Audi...
if I got a RS5, I feel like ECU tune + some minor suspension

Not sure I follow. The RS5's ECU has already been cracked and tunes are producing considerable power over stock.

Arin@APR has mentioned that they are currently working on a flash-from-home option, making map switching a breeze. Once that's ready, I'll probably get back into messing with E85 a bit, like I did a while back with the B8.5 S4. Especially now that an HPFP is available for the RS5.

At this point I'm thinking that once all is said and done, I'll probably have swappable 91/E85 tunes + HPFP. I've gone back and forth on upgrading the cooling system. However, for a car that will never see the track, it just doesn't seem worth it.

Also, if someone makes a decent quality non-CF intake for a reasonable price (~$450), I may consider that as well. I'm not normally one to care about intakes but after seeing the difference a simple aftermarket air filter makes on the C8 RS6/RS7, I'm now very curious to learn the true difference a higher flowing filter and/or intake makes on this car. I know we're talking two completely different platforms. But it does have my curiosity piqued.

Tried following the link. Didn't see what I expected... Is there supposed to be a page with a tuning option and the resultant power increases? Am I missing something?

Yes, but the 2.9L V6 is only for the 2020+ models. The accessport is for the previous models with the 3.6L V6.

Also, a high flow air filter will get basically all of the intake HP benefits. Intakes are primarily for sound.

My bad, I thought the link from my clipboard was right:
https://www.cobbtuning.com/products/...se-s-gts-turbo

This is the one - so that likely explains it (engine differences), on the page it didn't have the year, so likely no 2.9T available...once Cobb came out with the Accessport for the Golf R / S3, things changed quickly for the legacy ECU tuners. Right now you can move to new vendors without being tied through your investment to a single vendor who gives up support very quickly after they have a working tune, when the platform matures, the tune doesn't do the same.

[Bullhorn717]

Cobb would be super convenient if it existed...I remember changing maps on the fly when I had my Legacy GT. Even flash tuning custom dyno tunes with accessport etc. So versatile...and very reasonably priced.

Now You've got me thinking back to my STI days. The Accessport was truly ahead of its time. If we had that now, I'd be all over it.

That said, I do believe APR has something similar up their sleeve, which they've been developing and keeping close to the chest.

When I had my car flashed with the APR tune last Summer, they sent me a document, which included multi-page instructions on map switching between up to 4 different tunes, using the cruise control stalk. Here's one of the pages:




Since then, they've said little to nothing about it, until Arin just recently said this in the APR B9 RS5 2.9 TFSI thread:

There isn’t. We’re working on an at home reflashing solution.

Flashing at home would be great. However, even if I had to go to an APR dealer to have the tunes flashed, having the ability to switch between OEM, 91 and E85 tunes on the fly would be truly amazing

Just reading through how some people seem sort of disappointed with the power output of these cars modified or stock and wanted to see if people really bought these to tear into it and modify it.

I bought the RS model so I don’t have to modify it at all beyond maybe wheels. It’s pretty sick from the factory already. To me, it’s more than fast enough. I don’t track this car or take it to drag strips. It’s just a perfect well rounded car for what it is.

Wondering what most of the owner intentions were purchasing this car knowing there isn’t a lot of aftermarket support to begin with. The offerings I see is pretty pathetic other than wheels and extremely overpriced minus maybe the JB4. Just my thought. I know it’s your car and do what you want with it etc. I’m just curious and bored at work. Lol.

Well, I have not even broken my car in yet, so I cannot yet truly determine whether or not I will feel compelled to modify it or not. For me, modifying is power (HP&TQ) only. However, I did in fact buy it with the intention of adding power. I was planning on what I believed to be a fairly modest goal of approx. 500HP and 550TQ. I originally believed I could get there with a CAI and a tune, but I now see that is NOT an easy task. Not if you want to keep your FACTORY warranty. Hopefully the car will be fast enough stock, but I tend to think I will feel it lacking. It seems the APR 91 octane would get me there, but, bye - bye warranty, since I only want to work with dealerships and not a network of APR dealers. This is going to be much more challenging than I originally anticipated.
