First off I will start off by saying I am extremely disappointed with the performance of my A4. So I called ATP yesterday and they told me that they can do a GT28RS kit for my car for 24 hundred. "Hardwar Only" They claim 300hp to the wheels with this kit. Does anyone have any recommendations or knowledge of how far I can push the car before I run into reliability issues and start breaking stuff. Basically how much can the 1.8 take. I was going to go with the Neuspeed upgrade but just doesn't seem worth the money and I know I won't be happy with it. I want something more along the line of what the guy with the Blue A4 with 4RINGER on the plate has. Can anyone put me in contact with him so I can get some idea of what to look for and computer programs to run to make this work. Thanks to all who help.
