Stage 1 of this Six-Pack Power Chip is for stock or mildly modified engines, burning fuel at peak efficiency for better mileage. Fuel and timing curves are optimized for low octane, but mid-grade octane gains even better. Stage 2 is for performance applications that have aftermarket intakes, mass air sensors, and TBI spacers, among others. This stage offers the most horsepower and torque and requires a 180° thermostat, a free-flow exhaust, and 91 octane.

Stage 3 of this chip is for economy driving on highways and long trips as it optimizes fuel and timing curves for 87 octane. Stage 4 is for towing and hauling trailers with fuel and timing curves modified for 87 octane or better. This stage improves mid-range passing and low-end torque.

Stage 5 of this Jet Performance Products Six-Pack Power Chip (287056P) restricts fuel delivery and RPMs, prohibiting unwanted driving mishaps by valet parkers, teens, and anyone who is not you! Stage 6 is a built-in security device that cuts off fuel to the injectors so the engine remains off.
