Hypertech Max Energy Programmer Reviews

2005 Jeep Grand Cherokee Hypertuner

Reviewed By Bruce S (MARION, WI) Reviewed for a 2005 Jeep Grand Cherokee —4/17/2014 6:39 AM

Installed the program on my Jeep, you can program thermostat, tire size and regular or premium use fuel settings. Seems a little snappier, off the line but as far as huge performance gains, I'm not seeing it . Gas mileage is up approx. 1 to 1.5 mpg so over time it will pay for itself. i originally bought the unit to erase DTC codes after the N23 recall. It erases the DTCs and is very easy to use. Had bought a Superchips programmer but they do not support the 2005 Jeep 4.7 liter motor, Hypertune

So far so good. I went on a 200 mile trip with a full tank of gas and got 24.2 mpg. Not bad for a full time 4x4.

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.
