- 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 spectrum, 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.

2019 GMC 2500 HD Denali
Absolutely could not be happier with my Stealth Module, instant throttle response, more power and torque ( not that it needed any). I pull an equipment trailer and module does everything as promised and then some. I haven’t had it on long enough to estimate new fuel mileage, but I’m impressed and so is everyone behind me

Completely blown away by the difference the stealth module makes, I bought it for the mpg but would buy again for the power increase, truck has no lag at all, medium mode is the best for me and has the best mpg, but I use high on long trips or if you want to drive fast. I had 1800miles before it with an average of 12.7 mpg, now with 1800 more miles my average is 16.1 and I’m driving faster now to boot, I’m definitely a believer and the installation only took 5 minutes, great buy

Having had diesels in the past I knew of the dreaded turbo lag. I knew I wanted something to eliminate that on my new tow rig. I wanted something to give the 6.6L Duramax a little more pep as it has plenty of power already. Did a little research and settled on the Stealth Module. The module was very intuitive and easy to install. After the install I had to take it for a quick test drive. Set the dial to everyday mode and instantly noticed better throttle response and almost no turbo lag. Two days later I set the dial to heavy tow and hooked up to my 10k camper and headed for the North Georgia mountains. I caught myself constantly having to monitor my speed and ease off the throttle. The power and torque was plentiful. I just waived at all the other trucks with their sleepy engines as we blew by them going up the mountains. I felt as though the truck had endless power and speed, never felt like I needed more. Over all the module has performed as advertised and perceived value is well worth the cost. Great job Stealth Performance Products.

It has increased my mileage by 3 miles to the gallon and the power is good

Been using it everyday pulling mini ex and skid steers around and love it so far. The power difference is very noticable and unloaded fuel mileage is 2-3 mpg better but not without a trailer of some kind very often! Does exactly what was advertised.....very happy!!
