I will make one calibration change for an additional $100 per change. For example, changing a shift point for a given gear is $100 vs changing a shift point and a pressure setting would be $200. That value can be used towards the full custom tuning price.

ZL1 converter shuddering with heavy throttle

Hey, just did a 6.2 swap from 5.3 in my 2012 Yukon. The car drove very smooth before with the stock stall. I figured the Zl1 stall would also be just as smooth part throttle, but the car shudders a bit with heavier throttle, almost like a very slight bucking. Am I just trying to lock it at too low an rpm? Seems ok above 2000 RPMS.

Do I need to change anything with the TCC slip or pressures?
