RANGER 3.0L EFI AUTO 2003

The JET Module for Ford applications optimizes ignition spark advance, air/fuel ratio, transmission shifting, and various other parameters for ultimate power gains. It is designed for stock engines or mildly modified vehicles with aftermarket intake and exhaust systems. This plug-in module attaches externally to the vehicle's computer, potentially adding up to 25-30 horsepower. JET's exclusive Dynamic Spectrum Tuning provides optimal performance across the entire power band, improving throttle response, acceleration, and low-end torque. It is also 50-state smog legal. While daily drivers can use regular fuel for potential mileage gains, mid-grade or better fuel is recommended for optimal performance. Installation is simple and takes less than 30 minutes.
