"My truck feels a lot different when I installed the Gt tuner on performance, and it's a really good performance chip."
"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."
"Completely satisfied with the product, expedited shipping and the price was better than any other place I searched! Will definitely do business again!"
"It lived up to every thing I wanted."
"So far it's great, I bought it to make sure my truck was running ok and to monitor gauges."
