I'm just trying to figure out whats wrong with my car. In march of 09' the car did 131 in 4th gear with a 26" tall tire on the dyno, now in 2010' same dyno but different days the car will only do like 120 in 4th gear on the dyno.
I haven't change anything to the car drive line. Soooo what in the hell would cause this to happen?
