"But as I have purchased Superchips models before to use on my Fords I had no problem using the Hypertech model on my Jeep Grand Cherokee Overland Hemi. Ease of use is always a strong point with me. My Hemi Jeep now runs the way I want it to and I am very pleased I made this purchase." —Henry K from Spring, TX bought a Hypertech Max Energy Programmer for a 2009 Jeep Grand Cherokee, 5.7L Hemi.
