I have a 2015 Chevy 1500 with 6.2 and 8l90. When the converter goes to engage it's almost like it's slipping into lockup rather than just locking but only on the initial lockup. Once it's engaged it holds tight. Wide-open throttle hits the rev limiter and cuts off before it shifts.

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.
