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, the engine receives better combustion quality, efficiency, and power output. The end result is more torque where you need it, improved overall drivability and vehicle responsiveness.
Keep in mind, your diesel truck’s factory safety measures stay in place. The module is a safe solution for everyday driving and towing.

Stealth Module 🕵️
- Detectable? No. Be sure to remove the module before taking your vehicle in for service.
- Impact of Installation? None! The Stealth Module plugs directly inline to the manufacturer connections.
- Potential of engine damage? We work within the stock safety parameters set from the factory.
- More low to mid-range power, improved drivability, smoother more predictable power all while leaving emissions intact and staying within the vehicles factory set safety parameters.
- Detectable? Yes. Traditional tuners leave a footprint on the ECM regardless if it is removed. Traditional tuners will void your vehicles warranty.
- Impact of Installation? Yes. Splicing of wires and other modifications are usually necessary.
- Potential of engine damage? Yes. A tuner can cause the EGT's to be too high, create higher cylinder pressures
- Pushes the truck outside of the factory set safety parameters. Will cause excessive wear on vehicle parts by changing injector timing and duration, throttle input mapping and temperature limits.
