Great Product

Reviewed By John C (Stamford, CT) Reviewed for a 2004 GMC Yukon XL —6/19/2012 9:49 PM

I own a 2004 Yukon XL Denali and initially it could not communicate with the car; however, after 5 minutes on the phone with a Superchip representative I found out what fuses to pull and easily tuned my truck. It is now running tip-top shape in performance mode and in gas saver mode, responding beautifully with 3mpg increases. Thanks AutoAnything!
