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.

The Stealth Module provides:
  • Improved overall drivability and vehicle responsiveness
  • An increase in low to midrange power where you need it
  • Smooth and predictable power across the low-mid RPM ranges prevent the transmission from struggling to find power and hold gears longer
  • Safe for towing and everyday driving -while improving performance!
  • Increased hp**
  • Reliable torque increase, up to 120 ft-lbs**
  • Includes all-weather factory style OEM plug and play connectors for quick and easy installation
  • Engine operates safely within manufacturer parameters
  • Factory safety measures/fail safes stay in place and are not overridden or bypassed.
  • Stealthy technology does not leave a footprint in the ECM
  • No external OBD II monitors and supplemental devices required.

    Selectable vs. Non-Selectable
  • The selectable module includes a switch with 4 positions: Stock, Low, Medium, and High
  • The non-selectable module does not include a switch: Preset in the Medium mode
  • Mileage is impossible to guarantee with any modifications. Anyone that claims otherwise you should be very leery of. The majority of Stealth Equipped vehicles do see a mileage increase due to using the efficient low-end power our 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.
