I am a customer from Billings MT, and have taken my mk5 gti to Avalon twice for various performance upgrades. The first time I came down was for the APR stage 1 software, which changed the performance drastically. Brian, Phil, and the guys at Avalon really impressed me with their customer service and knowledge about Audi/VW vehicles, so the choice was easy when it came time to modify my gti further about a year later. After discussing different options with Brian, I decided to go with an AWE turboback exhaust, carbonio s2 intake, forge diverter valve, AWE boost guage, Awe outlet pipe, and eibach coilovers. All I can say is that this car is a monster now. It sounds amazing, handles superbly, and literally spins the tires thru 60 mph if you want it to. The installation was grade A++, and have not had one single hiccup with the car. Once again, the customer service that I received was excellent, and the work was performed in a timely manner. I couldn't be any happier with my car, and I look forward to driving it every day. I highly recommend Avalon motorsports, and couldn't imagine taking my VW anywhere else.
