"This is a must have if you want to give new life to your Jeep. Installation was a little more involved since you had to remove the ECU to install the chip. Added at leat 1 mpg, may not be much but in the long run it will pay off. It also smoothed out the idle.I have also installed a K&N cold air intake and a magnaflow muffler the combined modification, is phenominal! Increase torque and horses thru out the the RPM, ease of passing when on the free way. Magnaflow exhaust installed is pretty mellow and not too loud, especially when you open it up. The K&N cold air intake was louder than the magnaflow. It feels like driving a new jeep after the mods. Keep your lead feet off the gas pedal and you will see improvements in MPG." —Jerry A from Barstow, CA bought a Jet Performance Module for a 2000 Jeep Grand Cherokee.
