"My truck feels a lot different when I installed the Gt tuner on performance, and it's a really good performance chip."

"I have owned the Cortex and this does the exact same thing. This one can only be used on one vehicle, that is the only difference. Woke my Denali right up, it has never run so good."

"Installed in my 2011 Sierra with the custom dash mount, took about 20 min to get everything in and working. Very easy to install and looks great! Several custom tunes to choose from on the device, or go to Edge website and download others."
