Suuuuuper easy to use

Reviewed By Jon L (BEAVER DAM, WI) Reviewed for a 2014 GMC Sierra —12/5/2014 8:11 PM

Easy as can be right out of the box. I even used a Mac and had no issues updating the device. Simply plug it into your vehicle after updating, pick your desired tune, let it do its thing, and done. Installing tune took less than 10 mins total. Capped off with the Diablo Sport OBDII cover. I plan to have a custom tune written by DiabLew once I'm done installing different exhaust components to maximize everything's potential.

Daily driver that needed a little more pick up

Reviewed By Thomas B (FLORENCE, AL) Reviewed for a 2011 GMC Sierra —11/27/2014 4:28 PM

I got this to add that little extra to my truck, running the premium tune (92octane) I can tell a quicker pick up on acceleration. Fuel miles you won't really tell a huge differance until you run it on the highway, there you can tell both increased HP when passing and better Econ in the higher speeds. Overall happy.
