I've got an LS3 in 2003 my C5Z06 with a 232/240 @ 112 Pat G/Cam Motion cam. I'm trying to clean up the part throttle bucking from 1600-2200. I've removed timing in lower load cells (running around 22-24 degrees in problem areas) which seemed to help a little, and latest tune I commanded ~13.8 AFR to richen it up a bit between 1600-2400 by setting PE enable TPS to 0 in those cells and 1.063 EQ ratio for the same RPM's. That made it better, but there's still some slight bucking and I'd prefer not to have to run PE in part throttle. Any other suggestions? Tune is attached. Thanks
