i was racing a 97mustang on saturday, the attitude starts churping that my egt's are at 1350, i look st the tach and its at like 3100rpm. when i lifted the hammer it shifted, slowed down and hammered it again same thing...btw i was in tow/haul. i had my dealer run codes, there wasnt any codes motor or trans. tried changing the fuel filter and have yet to try it i will keep you all posted. i was also in level4.

any 1 else experence this?:confused:
