6L80E / 6L90E Transmission Tuning

Click on the "SUBSCRIBE" tab to sign up. I will not respond to technical questions unless you are a paid subscriber. Calibration and Config files will not open directly from the site, they must be downloaded to your computer in order to open.

NEW!!!

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.
