I was looking through and old issue of mustangs and fast fords and i saw and article about taking the stock intake and boring it out to allow better air flow then they added an aftermarket throttle body, they said you could use the stock one too if you wanted. I have two questions, 1) has anyone bored out their intake and howd it turn out? 2) i am probably getting a performance chip, and i know the chips are calibrated to the stock components and i heard if you change your throttle body size it wont really work right is this true anyone have any experience with this?
