It works I can feel the difference on top end and throttle response is much better.

Does exactly what they say it will. No more annoying 4 cylinder mode! Only thing I wish it had was an on off switch. Can't believe that if they were smart enough to design this device that they couldn't include an on/off switch. The plugging/unplugging issue is a PITA if you don't drive your vehicle every day. Hopefully they will come out with a fix.

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!
