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!

Worth the $$$$

Reviewed By Matt E (MIDDLETOWN, MO) Reviewed for a 2012 Dodge Ram —3/1/2015 9:07 AM

This was by far the best mod I have bought for my truck. Totally woke the 5.7 hemi up! Installation was a breeze and I got to turn the dreaded MDS off so no more drone. Took maybe 15minutes to save the stock tune and program the new tune. Totally recommend this to any dodge/ram owner.
