Works with:

  • Chevrolet/GMC years: 2016, 2017, 2018, 2019, 2020 LWN
  • Chevrolet/GMC diesel models: Colorado/Canyon

    The Colorado/Canyon Duramax LWN 2.8L Stealth Module provides: 

    • Better throttle response
    • Decreases turbo lag
    • An increase in low to midrange power where you need it
    • Reliable torque increase
    • Safe for towing and everyday driving
    • Stays within stock safety parameters
    • Stealthy technology does not leave a footprint in the ECM
    • Smooth and predictable power across the entire RPM prevents the transmission from struggling to find power and hold gears
    • Includes all-weather factory style OEM plug and play connectors for quick and easy installation

    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:

    • The selectable module includes a switch with 4 modes:
      Stock, Low, Medium, and High

    Mileage is impossible to guarantee with any modifications. Anyone that claims otherwise you should be very leery of.

    I have the 2.8 Baby Duramax. I love the engine but needed something to help with the turbo lag and give it just a little more power. I also didnt want to deal with a delete and tune. I have dont that in the past with other diesels I have owned and felt it to be cumbersome and risky with factory warranty. So I got the Stealth module. I like how quick it was to install and I keep the selector switch under the hood since I dont need to change it. I love the power increase I got without risking damage to my motor or exhaust manifold. Also eliminated the turbo lag. Good stuff. Tha is for a great product.

    I researched for quite some time before I decided to get my Stealth module. It sounded like one of those too good to be true kind of deals. But all the things I was reading in everyone else’s reviews of the produce were spot on! My throttle repsonce is much more crisp. My fuel economy is much better, when I keep my foot out it. And the low/mid range torque is definitely noticeable. I log about 35,000 miles per year on this truck and tow a loaded down enclosed trailer 50% of the time. Now I feel more confident if I need to pass that the power will be there and that when I hit the pedal there won’t be such a lag before something happens. Thanks for the great support and great product! My Duramax Canyon definitely has a new attitude.

    I have a 2016 GMC Canyon 2.8l Duramax and it has been lacking get up and go especially with the dead pedal. As I have read through the reviews I agree that the dead pedal is virtually gone and the pick up is amazing. I have also noticed it does not take as much pedal to get to speeds anymore. I have used all the settings and seems to work well in all settings but I chose to leave in the 3rd position. I have not been on a long trip to check for an improvement to the fuel mileage. Eric was very helpful on the phone even late at night when trying to get this module hooked up. The instructions were easy and correct just one of the connections was a little troublesome.
