JET Performance Module for Jeep Commander

The JET Performance Module for Dodge, Chrysler and Jeep vehicles provides power gains across the entire power band (not just at full throttle). By optimizing point by point air/fuel ratio, ignition advance and various other tuning points the JET Performance Module can provides performance gains of up to 25 horsepower.

Modules are available in two configurations: Stage 1 and Stage 2.

The Stage 1 Module is recommended for stock or mildly modified vehicles. Programming is designed to burn fuel at peak efficiency, increasing mileage while using regular fuel (for performance gains the use of mid-grade or better fuel is recommended).

The Stage 2 Module is recommended when the end goal is increased performance. It features more aggressive programming to make the most horsepower and torque available. Fuel and timing curves are extensively modified for peak performance. Requires use of 91 octane fuel, 180 degree thermostat and free flow exhaust. Also works well with aftermarket intake systems, mass air sensors, TBI spacers, etc.

You can go to the JET's website for FAQs regarding performance, suitability, environmental compliance, etc. In this page you will find the model numbers for the Stage 1 and Stage 2 modules that fit the Jeep Commander's three engines: 3.7L V6, 4.7L V8 and 5.7L V8. And, if you go to this page you will find a write up and pictures by a guy who actually installed and tested one of these modules in his Dodge truck's 4.7L V8.

While so far I haven't been able to find any Jeep Commander owner actually using the modules, there are a couple of Jeep Grand Cherokee owners (4.7L and 5.7L Hemi) in JET's Testimonial Page that apparently are very satisfied with the results. If you are a Jeep Commander owner who has tried the modules, please feel free to add your comments.

First impressions: I installed my Jet Chip. I did the battery unplug for 30 minutes. The chip is VERY hard to push on (all the way). Make sure it is on or the check engine light will come on. Mine did. I drove pretty mildly and noticed "shift points" were much better. Did a couple of "romps" (0 to 60ish) and found the power curve around 35 to 60 MPH was improved too. Overall, on a scale of 1 to 10 I would rate it a 7 but I am pleased with it. I will see if mpg improve next. While this a new install, I feel the XK computer also needs to "learn" this new addition. Idle is nicer and smother too.

Does the CHIP void the warranty? How about the other upgrades such as the exhaust, sway bars, cold air intake. Do these items typically void out a warranty?

Bought the stage one chip for my 2006 jeep commander 4.7L. Noticed rain water drips on the ecm connectors. Worried that if I put the jet chip in, this will risk shorting out the ecm. Anyone have a similar problem. Might be able to put more weather stripping there. Any comments appreciated.

A performance chip is really amazing. It boost up efficiency greatly. It's low cost, too.
