Do you have a MY13 onwards RG Colorado Utility or Colorado 7 \ Trailblazer wagon? Want an additional 25-40% power increase for towing or all out HP, while still having improved fuel economy for daily driving? I have you covered.
Included for free is an updated transmission calibration for automatic owners (gear shift & torque converter lockup speeds) & I’m happy to work with you to customize your own shift strategy if you have changed rims/tyre profiles at no additional cost.
Manual “Dura2Max” Tune = $900
Automatic “Dura2Max” Tune = $1100
