Is there anything that would cause a stang to not have the power its supose to, but still run and idel fine?.... Its a 93 GT with flowmasters and a K&N filter plus a super chip.... It seems like its missing some power... Its got 77k on it. If im in 5th gear on the highway and go to give it more gas, it doesnt have any go to it, it takes it awhile to build up speed...its got the stock 2:73s in it. Well anyways, i dunno if its just me or theres something wrong. Whats the prob if there even is one?
