Finally got to the track last night. The truck fell on it's face right after launch. It shifted in the 4000rpm range when it should shift at 6700. It was shifting at 6900 on the street with 6700 in the shift tables.
I flashed another tune in it (370 motor tune) and it ran better on the 1st pass (motor 2) but fell on it's face again on the 2nd pass (motor 3) with the same tune.
On the way home I hit it from a roll in 1st. It broke the drag radials loose and got loose again when it hit second, right back to normal.
Launching from a dead stop is sending it into some kind of safe mode.
Any help is greatly appreciated.
Thanks in advance.
John
Also I can't figure out how to put the tune on here. It seems to be too big.
