Make your diesel have more efficient power and fun to drive with our Chevy/GMC Duramax 6.6L Stealth Performance Module exclusively for Chevy/GMC Duramax 6.6L years 2011-2016. Your module will be a stand-alone computer that simply plugs in under the hood of your truck.  It will not increase fuel volume, so there’s no need for any other modifications.  Make your truck work smarter, not harder!  Get that extra boost in performance without any harmful side effects.

Works with:

  • Chevrolet/GMC years: 2011, 2012, 2013, 2014, 2015, 2016 LML
  • Chevrolet/GMC diesel models: 2500, 3500

The Chevy/GMC Duramax 6.6L Stealth Performance Module provides: 

  • Better throttle response
  • Decreases turbo lag
  • An increase in low to midrange power where you need it
  • Increased hp, 120 ft-lbs of torque*
  • 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 range, and increased throttle response.

We integrate with your Manifold Absolute Pressure sensor (MAP) to allow control and modulation of boost pressure utilizing your turbochargers variable vane control.

MAP integration and monitoring helps further improve engine responsiveness while keeping boost within factory safe levels.

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 vs. Non-Selectable:

  • The selectable module includes a switch with 4 modes:
    Stock, Low, Medium, and High
  • The non-selectable module does not include a switch. It comes preset in the Medium mode

Why sacrifice peace of mind when looking for a little bump in performance?  No endless modifications or flashes to your trucks computer.  This is the easiest and safest way to give your truck improved performance.  A cost-effective approach to wake your truck up starts here.  Backed by a limited lifetime warranty, includes 24/7 technical support, and superior customer service.  Finally a high-quality, safe, and non-invasive performance solution your truck has been waiting for. See why thousands of diesel pickup owners are turning to Stealth.

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. You're welcome to reach out to us so we can provide you with any tips we have learned from first-hand experience and speaking to tens of thousands of diesel owners.

    Great improvement in gas mileage. Averaging 2.5-3 mpg higher on highest setting. Noticeably quicker at all speeds. Much more fun to drive.

    I have been thinking about installing the Stealth module for some time, but was a little skeptical. After doing some research and reading reviews, I took the Stealth leap. Totally woke my truck up! Great throttle response, and after a couple tanks of diesel I'm seeing an increase in fuel mileage.

    2016 Chevy Silverado 3500HD

    Since installing Stealth Module I noticed an appreciable increase in power. Almost hard to keep the foot out of it. Towed 18,000 lb fifth wheel yesterday and got close to 14 mpg (up 3 to 4 mpg). Trip back unloaded was 18 to 19 mpg (up from 15). Granted towed vehicle was at 55 mph and unloaded was at 70 mph. Extremely impressed with the Stealth Module and can't figure out why I hadn't pulled the trigger sooner.

    2016 Chevy Silverado 3500, 6.6L Duramax

    I bought the Stealth Module for my brother for Christmas, and at the time, he was averaging 12.6 miles per gallon doing mainly in-town driving. We hooked up the module and set it on the #2 setting, and after 2 tanks of fuel, he's seeing 14.9-15 mpg regularly, and has even gotten as good as 17 on the highway. There was a noticeably instantaneous difference in responsiveness and power once the module was hooked up... just 1 trip around the neighborhood and we could tell a difference, as the lag between the moment he'd hit the accelerator and the moment the truck would set us back in the seats was gone. To say he has been beyond pleased would be an understatement. One of the best Christmas gifts I've ever been able to give!

    With the lift and my 37s, it had a noticeable drop in mpg and it was a bit sluggish. Ever since I installed the module I have zero lag during acceleration and I’m getting an extra 3 mpg. Definitely worth the price!

    I had an Edge tuner pulling a 20,000 Cyclone 4150 on heavy tow haul mode and would get 7.5 miles to the gallon. Installed the Stealth tuner making the same trip as before and got 10 miles per gallon. At this rate it will not take long for it to pay for itself.

    So far so good had a issue installing it but even at 8pm I was able to be talked thru my problem, FYI it was not the product I had plugged it in wrong. 300 miles in midrange power towing and empty is better most of the dead peddle is gone! Mileage also seems to be up about 2mpg which is a nice plus.
