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

2020 GMC Sierra 2500 AT4 HD

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 6.7 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.

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!!
