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.

8L90 4-5 flare

Looking for advice on tuning a 2017 CTS-V trans. Running pump 93 all the shifts are crispy, but on full e85 the 4-5 shift is flaring like crazy. Any pointers where to start looking?

740whp/805wtq, stock convertor and stock trans.
