Great product. Really easy to install.

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.
