Not entirely on its own. See anything that would alter the stock timing curve to the advanced side would negate areas of the HPP3 timing advancement. CAI since they flow air in at higher rates and cooler by nature will add about 1 degree. HPP3 programs do 3 max, so the CAI plus whatever, once you get to 3 degrees, the HPP3 becomes useless. There shifting leaves alot to be desired and some have ruined trannies using it!!wht02x said:hmm i c so if u had a really good intake and you were already getting getting 10 horse then the progrMMER WOULD BE USELESS?
