Tune is noticeable, definitely more pep and power, just wish it was a little cheaper

Pretty easy to use for programming my truck, and can't argue with the outstanding results. Set it for the mileage mode and gained 1.5mpg (3 tank avg) and still have plenty of power for daily driving. Very easy to change mode when I needed to tow, then return. Also used it to correct my speedo for larger tires and diff; that was a little trickier. Using GPS and cross-checking with mile markers, it was still a little off (6%, down from 9%)). Had to adjust the settings I inputed to get right on (with-in 3%).

Before installing the 87 oct tune on my 2014 GMC Sierra, the gas pedal was stiff and the truck had a hard time getting out of its own way. Now it drives as it should have from the factory! More off the line acceleration and torque, plus a noticeable difference while towing my large camper.
