Stage 1 of this Six-Pack Power Chip burns fuel at peak efficiency, offering enhanced fuel mileage for stock or mildly mofidied engines. Fuel and timing curves are optimized for low octane, but mid-grade octane gains even better. Stage 2 provides the most horsepower and torque, making it ideal for applications with aftermarket intakes, mass air sensors, and TBI spacers. It requires a 180° thermostat, a free-flow exhaust, and 91 octane.

Stage 3 of this chip optimizes fuel and timing curves for use with 87 octane, making it the right choice for economy driving. You'll use this stage for long trips on highways. Stage 4 allows you to two and haul heavy trailers by improving low-end torque and mid-range passing. This stage modifies fuel and timing curves for 87 octane or better.

Stage 5 of this Jet Performance Products Six-Pack Power Chip (287036P) is for valet use, preventing unwanted driving mishaps by valet parkers, teens, or others. It will restrict fuel delivery to prohibit unallowed driving time. Stage 6 is the security stage, which completely cuts off fuel to the injectors so the engine can't run.
