Missed out on AutoAnything $50 rebate by 4 days:(! Make sure to have battery booster just in case. Bullydog updater not compatible with Mac, took multiple attempts to get the new download to the microSD card or for the pc to recognize the card.

Works as advertised

Reviewed By Clayton U (HUNTSVILLE, AL) Reviewed for a 2009 GMC Sierra —5/18/2016 6:29 AM

Works as listed. Easy to plug into service port. Engine seems to run smoother especially when shifting at slow speeds. Have not noticed any appreciable difference in MPG. Also have not noticed any battery drain by leaving it plugged in.
