Here is the info from the "chip site."
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. Available in Stage 1 and Stage 2.
*For 1989-Current Dodge cars, trucks and SUV's.
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.
So more performance with lower grade fuel. And you can use it with aftermarket air flow sensors. How many Dodges do you know with an air flow sensor or TBI? A gimmick with a capital G. Atro why don't you map the fuel and spark tables it produces and tell us how it makes more power and torque with lower octane fuel.
Sorry again Dan about stealing away your thread.
