Took off from a light pretty hard and missed third and went into fifth, it made a loud air pressure noise(like an air hose) but then i went back to third floored it the revs came up and BOOM! i let off of it then into fourth punched it again and BOOM again, drove it about two miles hammered it again through all the gears and no problem at all, any ideas? Sounded like the noise may have come from my side pipe, checked my CAI and the filter wasnt blown off so i dont know, wtf?
