This is the real deal folks. Works like a charm. Mileage has gone down about 1mpg but whi cares about that when it cures the AFM oil problem and all 8 cylinders are working as they should? A happy camper.
Does what it says

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!
