The Stealth Module is a stand-alone computer that plugs in under the hood. Our internal software meticulously works to optimize the factory injection pressure to amplify combustion efficiency. By bringing the fuel rail pressure to its desired pressure sooner it allows for finer fuel atomization and a more complete fuel burn. In turn, the engine receives better combustion quality, efficiency, and power output. The end result is more torque when and where you need it, improved overall drivability performance 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.

Yes! This is different from your traditional flash tuner. The Stealth Module does not reprogram or flash your ECM. In fact, we are working strictly within the manufacturers safety parameters. This means that anything the Module is asking the truck to do it is fully capable of doing already. If you remove the Stealth Module the truck would be 100% back to stock.
No other modifications, splicing of wiring, program download requirements or gages are needed. Just plug the Stealth Module in and you get safe, reliable power.

Mileage is impossible to guarantee with any modifications. The majority of Stealth equipped vehicles have reported mpg increases due to using the low-end power the module provides to keep their RPMs down and hold higher gears. With responsible driving habits it's not uncommon to see a nice bump in MPG along with an all-around better driving experience.
Please purchase for drivability benefits and consider mileage as a potential bonus.
