this is the real deal.if you are skeptical don't be. then again if you don't like more horse power and torque this may not be for you.Plus you leave it plugged in for track times and data enquiries.totally change the way my Mustang automatic shifts,so much authority.all joking aside could not be any happier with this programmer!
