ok. F1a94/6.0/6l80 So the car was running great. Heres what i did... I changed to poly motor mounts. i went from a 4.75" pulley to a 4", took some timing our, and i changed some shift points. I was driving trying to do a test hit- i could no longer manually downshift below 5th. It will go from 6-5 fine, but not any lower. I tried to roll into it to make a hit anyway. at around 5500 RPM it falls on it's face, pulls ALL of the timing.
My thoughts/guess is its trying to shift from 4-3 and its a 6l80 so it cant? i dunno Unless im missing something?
Log and Tune file in case anyone is interested.
