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.
I feel my YSI Would benenfit shifting closer to 7500 or so. It shifts right before 7k now. It's a built 6l80 but I haven't found much about guys spinning the 6l80s very high.
