Description: The JET Performance Module for Dodge, Chrysler and Jeep vehicles is a JET exclusive. Dynamic Spectrum Tuning provides power gains across the entire power band-not just at full throttle. Point by point air/fuel ratio, ignition advance and various other tuning points provide performance gains of up to 25 horsepower. Improves throttle response, acceleration and low end torque. Simple, plug-in installation in less than 30 minutes.


Jet offers 2 versions.


Stage 1 - For stock or mildly modified vehicles. Fuel and timing curves are modified for optimal performance and mileage using less expensive, lower octane fuels. Programming is designed to burn fuel at peak efficiency, which results in improved performance and mileage. Daily drivers can use lower cost regular fuel for potential mileage gains, but for optimal performance gains use of mid-grade or better is recommended.


Stage 2 - Designed for the performance enthusiast, the Stage 2 features more aggressive programming to make the most horsepower and torque available. Fuel and timing curves are extensively modified for peak performance and drivability. 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.

Pros: It goes in and comes back out easy
Cons: Jeep became sluggish and MPG went down

MPG went down to 10
Jeep became slow to respond
Real slow to take off in first
Weird smell from exhaust
Tech support gave me some BS about having to drive 150 miles to let it calibrate after i told them i drove 100 miles with it in

Pros: Easy Installation
Cons: Limited performance gains - Not what manufacturer quotes

Install is very easy. Performance gains are slight - but they are noticeable. Mileage does improve about 1 mpg on the highway (75mph on cruise) to 18MPG. But 89 octane fuel is required to achieve the full performance gains.


I also installed AIRAID filter system with the Jet chip so performance gain is probably the result of both products. Much better performance overall than with stock engine.
