I have a ctsv that makes around 840hp boost only and 1050 or so on nitrous. The tune is scaled bc of the injectors and has a 5 inch intake on it. I have messed with the Virtual trq to get the trq readings correct but if shifts hard in the 2.3 shift and 3.4 shift will shift but takes too long and flares before it shifts. Car has a 28 inch tall tire on it.
Highly modified CTS-V 3-4 shift

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.
