"Absolutely 100% happy with this product. You can feel the difference instantly. Although Stealth doesn’t preach fuel mileage, which I completely understand due to many different factors, I’ve noticed significant fuel mileage increase. 20-24mpg driving it conservatively on the medium setting. This thing will pay for itself in no time. Thank You Stealth!!!" - Jim Y

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.
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.

Very easy to install the more I use it the better the truck gets better fuel mileage about 4 1/2 miles to the gallon. On the freeway better. Shifting points are better a lot less lag on the turbo.
With all the options out for performance improvements it was hard to decide what road to go down. My truck is just used for family and work. Was not looking for crazy power gains. Found the stealth performance module and after a lot of research and calling the company I placed my order. Shipped fast and arrived early. 5 minutes to install as I just left the switch under the hood so I didn’t have to fight to get through the fire wall. I have had it installed for a month. Amazing results. Just like everyone has said in other reviews it is awake. The low end power has improved and the overall responsiveness is much better. Little to no turbo lag. Could not be happier. I would definitely recommend to anyone.
I got the email Monday saying it was delivered. I went home shut the truck off for a hour then installed it. Just as promised it was a very easy install then I idled out my driveway to the main road as soon as I gave it a little gas I could tell right away something was different I was almost in doubt until that moment. I have a 2004 f-350 I’ve been driving this truck for 16 yrs have 380,000 miles on it and it’s been very good to me but I was not expecting the wake up. Haven’t hauled anything yet but I will leave a comment when I do Thx jimmy
It is super easy to install and to my surprise my 6.0 has never been more responsive on the low end. If you are wondering, does it really work? YES, it really works, and it feels like a completely different truck. I think it's a pricey device, and $600 is a lot of money however you will be surprised, like me, just how well it works.
Awesome product so far with very noticeable extra power and throttle response.
I have only ran this on #3 setting and I have noticed an improvement in low end response and did gain around 2 to 3 mph. So far am happy with this product.
Really glad I got the stealth. It woke my 6.0 up. It put the pep back in its step. Thanks!
I am happy I bought this. It works. Huge difference as measured with the seat-O-the-pants meter. Can't tell you about the mileage but when the wife got in the truck, she angrily asked what I did to it. It woke that truck right up.
I did some research on quite a few tuners for Diesel's. The best reviews and safety aspects came from Stealth customers so I bought one. Right off the bat I noticed a difference in the mileage and the disappearing of the turbo lag. Gotta say it was well worth the purchase and I do recommend this product to Diesel owners.
Blown away with results! Way better power and getting better fuel mileage to boot! Thought I had an issue and their customer service was excellent on helping figuring it out. Would definitely buy more if I had more diesel pickups.
No more turbo lag. So far so good. excellent customer service!
The difference in the power and fuel mileage in my truck from this module is astounding. 2007 F350 Crewcab Dually 6.0, before installing fuel mileage was around 14-16 mpg, after installation 73 mph on the interstate running empty on the fourth setting truck was getting 26.4 mpg, dropped to 24.2 at 60mph. Very pleased with this purchase so far, the real test will be pulling our 40ft toy hauler. I’ll do an update on that later.
Total improvement in throttle response and power. I'm running it in medium for now,can't wait to see how it pulls with my travel trailer. I also did see a little increase in m.p.g.
Absolutely love the box. Getting 23 mpg in a crew cab dooley.
I was hesitant to order the Stealth Module, but after reading reviews and seeing that the module keeps its adjustments within manufacturer engine specs, I pulled the trigger on the purchase. And boy I'm glad I did. I installed the module in less than 15 minutes and went for a test drive. Throttle response was amazing! I've had to relearn how to drive my truck now. I then hooked up our 30' travel trailer for a 3 hour trip home and I was more amazed. Using position 1, I was able to use cruise control pulling our 10k trailer when I've never been able to use it before. Was able to leave cruise engaged for approximately 2 hours before the hills became a little to big. Haven't checked it for any mpg gains yet, but I'm assuming it has increased as the fuel gauge seems to move slower. I am truly happy with the Stealth Module!
So far so good I’m about to pull a camper about 500 miles so it should tell the tail , It is getting awesome fuel mileage now!
Unbelievable how well this product works. I have instant throttle response and lots of power. Love it.
Quick service, easy to install, noticeable difference. I have seen a difference in power and torque. Loving it so far. Thanks for everything.
I love it on 1 it tows my 40’ camper with no problem on 4 she gets up and goes thank you
