[QUOTE="rattle_snake, post: 14842306, member: 126699"] I have taken 4 data logs at different times and looked through them. I cleaned the air filter and MAF. Car still pulls strong, without gauge I wouldn't know its dangerously lean. Battery voltage is weak, as low as 11.0V on one log. Usually when alt or bat is low car runs weak. Fuel pressure seems all over (33-45), but I looked at the logs from 2 years ago before and after the current tune and they are about the same. The top end is lean, also (sometimes) where bat voltage is low. Fuel pump DC is as expected. As any terminator owner should, I have a spare alternator to swap in and retest. Battery is new. Charging system wiring has the 'big 3' and has no corrosion. [/QUOTE]
