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.
