We also stock the STAGE 1 20305 for the same application. 

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.
