Reviewed By John P (West Hartford, CT) Reviewed for a 2011 GMC Sierra —8/7/2014 12:07 PM

great programmer, Huge improvement. loving it. initial computer setup/update takes a while, be patient.. before i had the Hypertech Max Energy and wasnt that happy with how little customization the Hyper allowed. this has all the features of the Hyper and more.. speedometer calibration for new gears/tire size, disable AFM (DOD V4 mode) adjust shift points, Adjust shift firmness, it has several great preset tunes and the biggest selling point was ability to get a custom tune
