Reviewed By john c (EL PASO, TX) Reviewed for a 2014 GMC Sierra —3/16/2016 9:41 PM

I'M SATISFIED WITH THE PERFORMANCE ON THE VEHICLE. FUEL CONSUMPTION HAS DROPPED TO 17 MPH. VERY EASY TO INSTALL AND REMOVE.

One vehicle at a time

Reviewed By nathan s (MILLS, WY) Reviewed for a 2014 GMC Sierra —9/19/2015 5:38 AM

This is an awesome product. Installed right away and had a very noticeable difference just on my stock 6.2l gmc. I don't have anything modified yet but this still gave it bigger balls. The only bad part is even with the expensive price, you can only install on one vehicle at a time. You have to restore factory tune on last vehicle before new vehicle is set

Reviewed By C. S (cheyenne, WY) Reviewed for a 2014 GMC Sierra —4/18/2015 8:21 PM

Bought this to correct my speedometer and to get a little more power. I had to update the software on the programmer but after that it was easy to install and use. Good value.
