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.

2009 Silverado

I have a 2009 Silverado with a Yank pro truck 3600 stall that is doing something weird in first gear. Launch starts a Frame 7000, around 7100 there is a rise in rpm that is very noticable. Is this transmission slip? If I raise pressure on the 1-2 shift does that increase pressure on the clutch up to the 1-2 shift?

Attached the Scan and File.

Please let me know if there is something I should try.
