New to the forum and kinda lost. I've got an 87 C-10 with a '99 Vette 5.7 and an '01 Camaro trans. Someone has already tuned it, but customer wasn't happy. I got an additional 23 hp from the truck as it arrived to me, but the trans is all out of whack. Traveling around 50 mph, if you stomp into it, it either goes neutral or revs up then slams into 2nd. I don't know enough about the trans tuning to know what needs to be corrected. If someone could look at it and help, would be greatly appreciated. If I need a log, I'll get it, just need to know which PID's to record. Thanks all.
