Can someone please tell me why I have very limited power from a standing start? It won't even spin a tire on dirt. This is a 2016 L96 with E78 ECM and 6L90e retrofitted into a 1988 Chevy truck. I have attached the tune file and a log file with several short pulls from standstill through 1st gear. I assume TM is doing this but really I am clueless. I searched tirelessly in and outside these forums, so if I simply missed the answer please help a newbie out with a point in the right direction. I'm hoping it's just in need of a few cells being tweaked...thanks in advance, Dalton
EDIT: I changed back to an older tune and logged. That fixed the problem but WHY? 2 new files attached.
1st 2 files are tune and log WITH the launch acceleration issue.
3rd and 4th files (before Doc) are an older tune and new log WITHOUT the issue.
