i know alot of people are gonna say get whipple, saleen, paxton, etc. but im not wanting major power just a little more than what i have now and i like the roush set up and the option to keep factory warranty. question is has anyone or know someone that has the roush supercharger on their shelby gt, i think the only difference as far as the standard gt goes and the shelby is the ford racing cold air induction. so im gonna put the standard factory air box in my car to accomadate the roush tune that goes with the factory setup. do you think roush will have a problem calibrating my ecm due to it being a shelby or is that besides the point since every car has a tune on it. has anyone had any experience in this and can anyone think of anything else i might need to do? thanks for your help, by the way great site!!!!!
