Hypertech Max Energy Programmer Reviews

Features are (car) model specific - ads are a bit misleading

Reviewed By Michael D (Wendell, NC) Reviewed for a 2006 Jeep Liberty —5/13/2014 7:54 AM

The programmer works well for the functions it covers, but there are several advertised options (shift firmness, shift point settings etc) that are not available for my car/unit. The advertising makes it sound like all options are available on all models

Hypertech Max Energy E-CON Reviews


Reviewed By Steven R (REDDING, CA) Reviewed for a 2010 Jeep Liberty —4/15/2013 6:37 PM

The device was very easy to install and tech was right there when I needed them but as far as econ its just not there. I have ran several tanks of fuel through and there has been no change in my milage. I will continue to test and hopefully it will get better.

Hypertech Max Energy E-CON Reviews

I't's a Hypertech tune, not E-con saving you gas mileage

Reviewed By Eric P (MORRISVILLE, VT) Reviewed for a 2010 Jeep Liberty —1/8/2013 1:20 PM

Loaded the tuning, for three weeks watched gas gallons, wrote down each fill-up miles. Have lost 2 miles per gal. Under stock 15 miles per gallon. Insted i was hoping to gain 2 miles a gallon. If you want a tune not a saving gas mileage tune i guess it's a good tune.
