"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

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.
You can find the installation instructions here.
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.

As description states & just what I was looking for. Did not come with the switch sticker but not a problem for my application. Unfortunately doing a full delete where I live is not a bright idea so this gave me the (legal) boost I was looking for.
United StatesEasy 15 minute plug and play install. Noticeable improvement in throttle response, low end torque and a 10% improvement in fuel economy. Have recommended Stealth products to several friends.

Just installed the Stealth on my truck and very impressed with the performance so far. Only thing is still trying to get the switch thru the fire wall and into cab. So far I love the response and torque. Awesome product.
United StatesOne of best tuner I found for my truck thanks keep up work.

Great Product. Almost completely eliminates the pedal lag. Has some get up and go. I keep mine on high and get about 1.5 to 2 more mpg. I drive mostly highway. But it makes it a lot more "zippy" in town. The Biggest problem I had was understanding how the safety lock works on the truck side and getting it released and unlocked. Spent 45 minutes unlocking and 5 minutes installing.
United StatesVery pleased with the increased throttle response and 4-4 improvement in mpg. Pretty easy to install in spite of tight clearance to access stock connectors. Kerry

Just the tech needed to make this engine come to life. Better mileage, power, pedal response and it’s all within stock parameters. The module is fairly easy to install. You won’t coal roll here but it’s worth the investment. My install is happening at a fairly new engine of 5500 miles. Thanks
United Stateshavent had any issues with it and fuel economy has increase too

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.

really like the performance
United StatesI 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.
Stealth tuner is awesome and fuel mileage is great
