I have the Ultimate race chip for sale Race Chip ultimate I have used this for the last year and it works perfectly, I never got a check engine light, and it takes 5 mins to install and remove.

Asking $200 + shipping they sell for $600+ Please take a look at the link below. Thanks RaceChip Ultimate
