i got a different mustang gt last week. dont ask why, long story. anyways its an 04 gt 5spd. one of the guys that i work with gave me a jet chip for that car that the customer never came to pick up. so now i have a jet chip to throw in there. are these any good? the guy who gave it to me put one in his 95 gt and said it gave him around 20hp and increased gas mileage. anyone here have one of those? im gunna throw it in some time this week and ill let u know how it works out.
