I have a 2002 acr with cold air intake, and i was wondering if a performance chip would be worth getting? And 1 more question...would installing a performance chip decrease my gas mileage?
Since you have an 02 just buy the A/Fx race PCM from Howell Automotive, the performance chips are total ****, but you do have an option that will give you 10-15Hp and has been proven.
