11 cts-v wagon, 12 psi boost, ID850's, Air Intake, Lid Spacer, 19in MT Dr's. Race weight is always between 4750-4770. Best run is 11.4 shifting at just about 6200 rpm. With stock cam etc, would I gain anything by maybe getting it to shift 6400 rpm? I've been hesitant to do so because some topics I had read about breaking valve springs, trans abuse, but also seen where others are shifting up at 6500 on stock cam, valve springs, and trans.
6200rpm shifts to conservative

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.
