Hello fellow A4 owners. I have a 2010 A4 2.0T (US) with a 6 speed manual gearbox and Quattro. I love the engine, but I can't help but feel that there's more power to be gotten out of the 2L. Has anyone had any experience with tuning the car, particularly through MTM or ABT? Or any other tuners for that matter? Are there reliability issues? Is there warranty? ETC... In short, I was wondering if anyone had either positive or negative (or both) experiences with this kind of project. Thanks, and keep driving.
You might consider posting on audizine, it's a much more active board.
In short, MTM/ABT/Revo/GIAC/APR/Stasis all have their own stats, but they're close.
There are warranty issues involved. Audi recently released a statement to dealers about it, but some dealers remain pretty open to it. I've not read of many chipped owners having extra problems, as the engine is definitely solid enough to handle more power.
Stasis charges more than the others, but will take care of issues that come up that aren't covered by Audi's warranty.
I wanted to go with MTM but they were a bit costly, have no function to switch to stock mode when going to dealers (does not matter anymore), and required shipping. Right when I picked the car up from dealers, APR had a sale, so went that route.
Honestly they will all be roughly the same. Stasis does not make theirs, just a detuned APR for more money and supposedly a warranty. Just get it tuned locally somewhere. You won't be disappointed.
