Just wanted to say that close to 1 year after the APR ECU reflash you performed on my 2002 Audi TT 225 the car is still running fantastic. If there are any other Audi TT 225 (or even 180) owners in the area, this upgrade is bar none! Forget the others! APR creates the most reputable, reliable, and professionally engineered product you will find anywhere! Fast Addiction had my TT in and out the same day I called! And let me say, it is most definitely worth it! Slap on a Neuspeed intake and Forge 007 DV, and your TT will be a whole new animal!!! Fast Addiction is the place to go for fast, friendly, and easy services for your Audi/VW! Thank you!
