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 .

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!

Works great!

Reviewed By Ba L (PORTLAND, OR) Reviewed for a 2014 Toyota Tundra —10/24/2014 1:15 AM

I have many friends who have this in their trucks and hear many good things so I decided to get one for myself. Throttle response felt much smoother. Works as advertise. Installation was straight forward and simple, plug and play.
