Equip your vehicle with a Jet Performance Chip and add up to 23 horsepower instantly. The Jet Performance Chip's simple, plug-in installation allows you to provide full range Dynamic Spectrum Tuning (DST) of your air/fuel ratios, ignition advances, and transmission parameters. Each program is dyno tested to ensure the most horsepower gains possible.
All Jet Performance Chips are 50-state smog legal and are available in Stage 1 (for original stock engines) and Stage 2 (for modified motors with performance air intakes, headers, or performance exhaust systems).
STAGE 1: For stock vehicles, fuel and timing curves are modified for optimal performance and mileage using lower octane fuels. Stage 1 Jet Performance Chips are programmed to burn fuel at peak efficiency, resulting in improved mileage gains.
STAGE 2: Designed for the performance enthusiast, Jet Performance Stage 2 chips feature more aggressive programing, making the most horsepower and torque available for your vehicle. Fuel and timing curves are extensively modified resulting in peak performance and drivability. Stage 2 units require the use of 91-octane fuel, 180 degree thermostats, and a performance exhaust system. Jet Performance Chips also work well with performance air intake systems, mass air sensors, and TBI spacers.
