Works great except a few glitches

Looks great. Love all the options. I wish it didn't require so many add-ons to monitor some things. I have had a few times that it froze up while loading and had to be unplugged to fix it. I updated to the current firmware before installing.

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.
