"Stealth Performance is badass. I towed my 5th wheel 41 almost 3000 miles and it towed flawlessly. Better gas mileage. Better pulling power. Better out of the hole feeling. Very happy with my purchase" - Michael G
Stealth offers a cost-effective approach to taking back your power and maximizing your truck's performance. You no longer have to sacrifice anything in the search for upgrading performance! No need for endless modifications or flashes to your truck's ECM. The Stealth Module is the easiest, no hassle approach to give your diesel a safe improvement of power and performance. Backed by a 1 Year Warranty your purchase includes 24/7 technical support and superior customer service. Finally the high-quality, safe, and non-invasive performance solution your truck has been waiting for.
Keep in mind, your vehicle's factory safety parameters remain in place. The Stealth Module is a safe and upgraded solution for everyday driving and towing tasks. See why thousands of diesel pickup owners and enthusiasts are turning to Stealth.
Yes! This is different from your traditional flash tuner. The Stealth Module does not reprogram or flash your ECM. In fact, we are working strictly within the manufacturers safety parameters. This means that anything the Module is asking the truck to do it is fully capable of doing already. If you remove the Stealth Module the truck would be 100% back to stock.
No other modifications, splicing of wiring, program download requirements or gages are needed. Just plug the Stealth Module in and you get safe, reliable power.
Mileage is impossible to guarantee with any modifications. The majority of Stealth equipped vehicles have reported mpg increases due to using the low-end power the 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.
Please purchase for drivability benefits and consider mileage as a potential bonus.
