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

Big Help

Reviewed By Casey Delorenzo D (Budd Lake, NJ) Reviewed for a 2005 Jeep Grand Cherokee —1/21/2014 12:08 PM

I got this tuner looking for something that could tune and show engine parameters. I chose this over the Flashpaq as I do own an Android device and I recommend doing that as it does have many extra features over the Flashpaq. I didn't expect too much of out this in terms of power, but it definitely helps pull 35's.

Second time around...

Reviewed By Richard P (Glendale, AZ) Reviewed for a 2005 Jeep Grand Cherokee —7/16/2013 10:49 AM

Same product was installed in my vehicle (Jeep GC Ltd, 5.7L Hemi) along with some other aftermarket performance enhancers when purchased... *Warning* It is "Extremely" important to note, that installation is made with a tight secure seal! Bad things will happen if water manages to leak into a loose connection. This time around I used electrical tape as a second measure. Disappointed I haven't received any boost in performance however, my MPG (Mostly HWY) has increased by roughly 12%.
