5.3 timing drop to -10 on accelration I have a l59 5.3 in my 1983 jeep. about half the time under hard acceleration it will fall on its face for a second then pick up and go again. A friend logged it on hpt for me and its dropping timing to -10 and then pics back up. I don't have hpt and he is busy. Can someone look at this log and help me figure it out? the log is around 20mins and it happend 4 times during the drive. sorry we didn't mark when it does it but its not hard to find. also pay no attention to the wide band as it is setup for my friends car not mine. Thanks. also attached it my tune, stock accept for the necessary things to make it run.

I don't have HPTuners anymore, so I can't look at the tune or log... might want to make sure he zeroed out the Traction Control spark retard tables - I have seen that do what you are describing when transplanted into a vehicle with no traction control.
