Hypertech Max Energy Programmer Reviews

New to me...

Reviewed By Henry K (Spring, TX) Reviewed for a 2009 Jeep Grand Cherokee —2/2/2010 6:38 AM

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.

Tuning experience...

Reviewed By Henry K (Spring, TX) Reviewed for a 2009 Jeep Grand Cherokee —7/3/2007 6:56 AM

So far I have only tried the performance tune for premium fuel and am satisfied with the results. I would have liked a 93 octane tune better than the 91 but all is well with my 4.0L Mustang as compared to the factory tune. The tuning time was very short and difficulty factor was very simple. Even a caveman can do it.

2007 Jeep Wk Lifted

Reviewed By Eddie C (NEWPORT, NC) Reviewed for a 2007 Jeep Grand Cherokee —3/20/2015 8:16 PM

Does the job as advertised. Recently lifted my jeep and put 31" tires on. Prior to installing the calibrator, the speedometer was off 7 mph. When reading 55 on speedometer, GPS showed me going 62. After calibrator installed, speedometer is dead on with GPS speed tracking. Would definitely recommend and may upgrade to the max energy software.
