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.

DiabloSport Trinity T-1000 Programmer Reviews


Thrilled with my Trinity

Reviewed By William S (Dallas, TX) Reviewed for a 2013 Jeep Grand Cherokee —1/22/2016 7:16 AM

I would definitely recommend this tuner/programmer to any car enthusiast that is looking to improve performance in their car. I will say that the canned tunes (the ones that are preloaded on the Trinity) did improve my car (Jeep SRT), but nothing like a custom tune that you can get from someone who knows what they are doing or one you can get when dynoing your car. The interface and software was really easy to use as well as the logging for the custom tuner.
