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

Bought to recalibrate speedometer to improve mileage, trans shift at correct RPMs, and accuracy back to stock-- it did this exactly as product was described. Very effective, very easy to use which is a big plus!

hyperpac pays for itself

Reviewed By Jason F (PALMETTO, GA) Reviewed for a 2005 Dodge Ram —3/20/2014 10:39 PM

Extremely ez to install. Just get in, close all doors, turn off all accessories, and follow. Performance went up est 15hp at least. Mpg average up 1.5 mpg. Up 3mpg hwy observed. Very useful, monitor actual water temp, trans temp and much more. Practical can potentially save a lot of money! Just be mindful that the gas pedal is more fun. Id buy again.
