This unit replaced a DS Predator. It performs much faster with better graphics and more features. It is also multi vehicle adaptable. Great product

2008 Jeep Grand Cherokee 3.7L

Reviewed By Peter D (LITITZ, PA) Reviewed for a 2008 Jeep Grand Cherokee —6/8/2011 6:43 AM

I have always wanted a "Performance Module/Chip". Jet is one company that a lot of people seem to talk about. It was easy to install and they said i would notice max performance after 200 mile. I just past that and I do notice a difference. is it worth paying over $200 for? I don't think it is. Not when it comes out to $14 per HP. The install took only 5 min. This chip is small so it is not an eye catcher. best part about it is that if something went wrong on my car i can take it out and take my car to the jeep dealer and they won't know i ever had it.

Hypertech Max Energy Programmer Reviews


nice upgrade for a 3.7 jeep!

Reviewed By Steven W (Rensselaer, NY) Reviewed for a 2006 Jeep Grand Cherokee —10/31/2016 2:10 PM

I bought this for my 06 jeep grand cherokee with the 3.7 V6. it has a 2 in lift and bigger tires (31's, i didnt want to go too big since its my daily). i bought the programmer mainly for tire size calibration for my speedometer, but i was pleasantly surprised by the performance increase from the tunes. great power increase across the RPM range, throttle response is instant (i also have an injen cold air intake), its no race car but its a nice addition. MPG's increased also. only con is price
