Personally I was going to leave the stock factory chip in my TTA. I figured with that old school programing I'd give it a try. I'm sure glad I did. I called Eric at turbotweak and had him burn me a stock chip. What a difference!!! My car ran soooooooooo much smoother. It also seemed like I picked up some HP. I was also getting some mild knock at WOT with the factory chip. That all went away. I love it! If you have a factory bone stock car, I would recommend getting Eric to burn you a chip for your TTA! http://www.turbotweak.com/
