ok i have a 94 mustang gt and recently had the transgo shift kit installed the car runs like a dream now but there is a big problem. when i get to 130 the car will over rev under wot but if i go 3/4 throttle it will keep goin. also the guy said i need to have my rear end calibrated ( 3.73) so really when im gon 130 its actually only 110 i never had this problem b4 the shift kit plzz help IM GETTIN BEAT BY RICER CIVICS!!!

Do you mean it slips under WOT? And definitly have it calibrated. It might be confusing your ECU.
