i'm looking to buy a performance chip and/or programmer for my '02 4.7 dakota 4x4 sport. the engine is modified (headers/exhaust, cold air intake etc.) but the biggest concern is if the calculations made by chip/programmer would be negatively affected due to the fact that both cylinder heads have been shaved .125 (they were warped due to overheating). would a programmer be able to compensate for the slight change in compression ratio?
