How it Works:

The module is a stand-alone computer that plugs in under the hood. The internal software meticulously works to optimize the injection pressure to amplify combustion efficiency.

By bringing the fuel rail pressure to its desired pressure sooner, it allows for finer fuel atomization. In turn, elevating fuel-air mixture. This allows for better combustion quality, efficiency, and power output. The end result is more torque where you need it, less turbo lag across the whole RPM spectrum, and increased throttle response. Keep in mind, your truck’s stock safety parameters remain in place. The module is a safe solution for every day driving and hauling.

Selectable Module:
