Was a little disappointed that I had to update the program straight out of the box, but the link and download worked easily and quickly. Has lots of set points, which is fun to tinker with. Since we only have 91 octane readily available in our area, I had to add octane booster to eliminate the pinging. Bottom end response is noticeably stronger, and the firmer shifting is just what I wanted. Mpg seemed to pickup a bit too, but that is offset by the needed octane booster.

2014 GMC Sierra 1500. Fairly easy installation. Manual days you need to remove several fuses, but this is not necessary. Just make sure headlights are off, radio is off, and nothing is plugged into DC outlets. Did what it said!
