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.

2-3 Flare after WOT Pull

I need some help tweaking my torque model... Having some issues with my 2-3 shift flaring/slipping after a WOT pull. It doesn't happen under all loads and it shifts fine and holds without slip under WOT. I'm hoping it's just needing a tweak to the torque model.

Built 6L80E, Billet Intermediate Shaft with Powerglide clutches and billet planetary. Truck is an AWD 2007 Yukon Denali, 402" LSA (14-15psi) making 800-850hp. I may have burnt up the clutches at the track last October but it has been running fine with the exception of this 2-3 shift slip under light loads. This has also all been since the cold temps, trans rarely gets over 120-130 degrees.

Logs and Tune Attached... Thanks!
