1999 Jeep Grand Cherokee 4.7L V8 4WD - Improved

Reviewed By Scott B (Frederick, CO) Reviewed for a 1999 Jeep Cherokee —8/14/2009 1:52 PM

Although most reviews and feedback from "experts" in the field indicated I would improve MPG by only 0.5 - 1 mpg, I have experienced a 1.5 - 2 mpg improvement. I drive at an elevation of 5000-6000 ft and use 85 octane fuel. Coupled with the stock replacement K&N air filter (not the entire air intake kit), this programmer has taken my jeep from 15 mpg to an average of 18 mpg. I would recommend this programmer; it will pay for itself within a year or two.

Great programmer, easy to install and use.

Reviewed By Clinton S (Tampa, FL) Reviewed for a 2001 Jeep Cherokee —12/20/2014 9:20 PM

I used the 91 octane program and I can tell the difference in acceleration and I don't have to get on it as much to keep up with traffic. Took 10 minutes to install and you can update it online.
