trying to chase down a very noticeable surge in power (bucking sensation) while doing a pull in 5th and 6th gear. i do not think its engine management related, i noticed the TRANS SLIP RPM pid has a very large negative value (what does this mean?) ...while both manually applying the tcc and unlocked tcc.
here is my current tune file 2nd dyno maf20 trans CATheatoff idlecoasttiming lowered minair10 dfco off brafetcmult.hpt
here is a pull with no tcc apply pressure (2:01 mins) trans slip 1.hpl
here is a pull in 4th with tcc applied (3:45 mins) trans slip tcc on.hpl
just trying to rule this out as a variable so i can continue my diagnosis. thank!
