"The JET chip is a good price compared to other device's. installing the chip was easy, find the cpu and unplug and plug the JET chip in and plug back in. I bought the stage 1 and notice a gain in Horse power and torque.. i have free-flowing exhaust and cut out airbox with a K&N filter, with a AIRAID spacer on my throttle body. It did very good i thought .. but one catch! it doesn't really save fuel since it's giving more fuel for performace.. but like the response and recommend it.." —Hans S from Anchorage, AK bought a Jet Performance Module for a 2001 Jeep Cherokee, Automatic, 4.0L 6-cyl..
