I've been reading about these performance chips and they say they can gain 10+ HP. Will these work on ATX Contours and is the change noticable? How much should one pay for these and how much do they cost on average?
PS- I know I'm posting a lot of questions, ones that I'm sure you have read over a plethora of times, but I just bought my Contour, and there is so much I want to learn about it and do to it, so please be patient with me. Thanks.
