I don't see a ton of action in here for the S7. I joined for insight, tuning support, parts availability, and information sharing. Either people are just gatekeeping around here, or no one else is trying to build one of these cars that we already have minimal support for.
I've googled and done a ton of homework on these cars, and really do not come up with much. I'd like to bounce ideas off others that are in the same boat here, but it seems like I may be the only one in here.
To date, I've done almost all the OBDeleven hacks I can find, some are valuable, some suck, but I stole the majority from the C7 forum and RS5 group. I had the Matrix lights enabled, almost $1000, and I was skeptical, but living in a rural part of town, its worth every penny.
I have the APR Stage 1 tune, it's a total waste of money and the gains are marginal and minimal at best. Save your money for custom tuning. Their support is there, but they are unwilling to make it right. Most of the features that are advertised on their site aren't available for our platform, and they say that's in their fine print, though I still haven't seen it.
Hardware wise I installed the APR intake.. Very nice piece, but the plastic secondary air tube flange broke from the carbon fiber tube. I looked online and found another owner that had the same issue. I used JB weld to repair it and its been solid... APR did reluctantly step up and send a new pipe out.
I installed GFB diverter valves, those are pretty awesome. They hold boost longer and make the butt dyno feel like you're making more power, while you're actually hold boost and using it.
Lastly, I installed catted high flow DownPipes. They are badass. They wake the factory sport exhaust up substantially. With the valves open she screams. The issue with those, the CEL is on for catalyst below threshold P0420 P0430. This is the same code for catless pipes. These are 200 cell pipes. I'm looking into electronic simulators, as any tuning to turn off the secondary o2's will fail state emissions test, as you will never get IM readiness.
Cosmetically, I have carbon fiber mirrors, a 3 piece lip wing for the rear, and some carbon fiber parts for interior accents.
I cut the chrome exhaust tips off and welded on Black Stainless quad tips, since that was the only chrome on the car.
I took the OEM black optics grille off and swapped it for the RS grille.
My tires just came in today, so next week, I'll have all black 21" ABT wheels installed and my red calipers will be blue when I'm done here.
its a work in progress, I'd post more pics, but hosting them here is a real pain in the ass, can't just copy/paste.
