Hi.

I just bought my first 2000 A4 & it's not what I expected to be cause I not getting as much Horsepower & the car is not running as well as it should be. I heard about a chip system that can make the car go faster so if anyone knows much about it let me know where to get it & info on how to install it & other info for my car. I planning on changing a few things on my car starting by fixing the enging morehorsepower, run well & than the interior & the wheels. So any advice would be great & fell free to refer me to website for more info.

My A4 need help.
