Stealth Module Ram Cummins 5.9L (2003-2007)

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.

• Improved overall drivability, vehicle responsiveness and performance
• Increase in low to midrange power -where you need it (Better take-off and efficiency through the bottom end gears)
• 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 horsepower and reliable torque
• 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
• Warranty friendly: must be removed before service
• No external OBD II monitors or supplemental devices required
• Selectable 4 position switch: Stock, Low, Medium, and High

Yes! The Catalyst Module is different from a traditional flash tuner. It does not flash or reprogram your vehicle’s ECM. Instead, it works within the manufacturer’s factory safety parameters, requesting only performance the vehicle is already capable of delivering.

Because no permanent changes are made, removing the Catalyst Module returns your vehicle completely to its stock configuration.

No additional modifications, wire splicing, software downloads, or monitoring gauges are required. Simply plug in the Catalyst Module and enjoy safe, reliable power.

Fuel economy cannot be guaranteed with any performance modification. Some Catalyst-equipped vehicles may see improved MPG as the added low-end power helps the vehicle maintain lower RPMs and hold higher gears. With responsible driving habits, better fuel efficiency may complement the Catalyst Module’s improvements in responsiveness and overall drivability.

We recommend purchasing the Catalyst Module for its performance and drivability benefits, with any improvement in fuel economy considered a potential bonus.
