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 range, 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 vs. Non-Selectable
- The selectable module includes a switch with 4 modes:
Stock, Low, Medium, and High
- The non-selectable module does not include a switch:
Preset in the Medium mode

- Turbo lag
- fuel economy
I have a stock 2018 F250. I wasn’t really expecting much— but of course like most people after reading all the reviews I said what the heck. I’m most impressed with the fuel mileage gains. I gained at least 3 miles a gallon. The throttle response does feel better but it takes 2 to 3 days for you to feel the full effect. The first night I put it on I really didn’t notice much on either the fuel economy or the pedal response but by day three it was very impressive. I have it on the highest setting. I haven’t tried any other settings.
19 King Ranch with 3.55 gear went on a 400 mile trip on selector 3 and got 19.5 mph doing 80mph most of the time.
Easy going staff , got me the correct unit in record time and it installs fast. I work on trucks a lot and I would rate the install on my 2014 a 2 out of 5 with a 5 being hard I choose the adjustable unit and recommend it due the adjustability modes.
Performance Module for 2018 F-250
First module did not work, they replaced it, after about 400 miles started noticing power creeping in. Also noticed truck saves about 50 miles on tank. So overall was good purchase.
Just purchased module for my 2019 powerstroke. I had A LOT of reservations because so many people on internet talking good and bad about these and especially touching upon the question everyone asks: "Will this void my warranty". I decided to go with it. I just installed it today. Ive got a 6 inch lift and running 37" x 13.5 toyo tires, and I am super impressed with the significant improvement with turbo lag and overall power. I was romping for about 20-30 minutes along routes I normally take to work everyday, which is city traffic, and i was getting 2mpg better driving same routes, but hard on the pedal. For me, if something breaks down, and the dealer can prove via the magnuson-moss warranty guidelines (which they are required to do per federal government) that this device caused the malfunction, I can afford to fix an issue, but I am very doubtful a device that does not change programming on the trucks computer, would be a direct cause of damage on a truck for any reason. Overall, I have noticed immediate improvement in MPG, overall power, and off the line turbo performance. I do NOT pull anything and so I did this purely for performance and better fuel economy. Even if I improve 2 mpg, over a year of driving its more than enough paid for this device.
I am very pleased with the performance of the module. The gain in power and throttle response was noticeable. I can now pass people on the highway with confident. Gained about 2 mpg on my daily commute. Not noticeable gain on fuel economy on towing my 14k trailer. But the power gain while towing is noticeable. Overall, best $550 I ever spent on an upgrage!
Very Happy Reviews I have read we’re correctt.
Installed today and turbo lag gone and super happy. Put 100 miles on truck after install and so far all claims are true from my test driving. Will update after couple weeks but bet I will feel the same.
Does what it says it’s supposed to
I put new tires on my truck (35”) and of course noticed an immediate drop in fuel mileage and a “loss” in power. I ordered this in hopes of getting at least some of those losses back. I had an issue with the first module I was sent, but in no time they had me another sent out. Once it was installed it felt like I had my truck back. Plenty of power now, it’s like I never put the bigger tires on and so far my fuel mileage seems to be back up where it use to be. Only thing I wish it had was a indicator ring for the switch so you knew which setting you were in at a glance.
Better MPG but no noticeable difference in horsepower.
Its worth it for the better MPG very hard to find and plug into fuel pressure regulator. The variable switch needs to be marked. Overall , a few cuss words and its installed and your on the way to better mpg.
2016 F 350
10 minute install once you find the plug. I average 16 miles to the gallon in the top selection switch. (It would be helpfull if the switch was marked!!) Turbo lag is noticeably less , I went from Miami to Atlanta and averaged appx.18 mpg. Which is considerably better than before.. (80 mph for most of the trip empty)
Mardi Gras Foley, Alabama
Can definitely feel the difference in power.
Great customer service answers phone anytime of day
Love the stealth performance programmer. Quick response to the get up and go now.
Great product sooner easy install
I have had stealth for over a year and 50,000 miles and love it . What just set stealth above the rest was I had an issue with mine and they just issued me a new one and return label for old one. You got a customer for life guys . Excellent customer service
It's just as they said.
It's just as they said...only thing is I'm having a hard time keeping my foot off the pedal...to much fun...haven't pulled my trailer yet but next weekend coast bound and we'll see how she does
Extremely pleased with the Stealth. Great improvements in performance and a little help at the pump.
Don't be skeptical
Like others I researched this module for months before pulling the trigger. Don't waste your time researching...just listen to all the positive reviews and buy this module. I just installed it and my F-350 with a 140,000 miles on it feels like a brand new truck now. The throttle response is on point and I notice very little turbo lag now. Great product!!!
Installed the module minutes after ups dropped it off. I was rather anxious to try it out.Took about 20 min in my driveway with temps in the single digits...including running the selector switch through the firewall and mounting that. Truck is deleted with H&S tuner,S&B air and 5 inch exhaust,35's and a 6 inch lift. Aside from wanting to stop the turbo lag I bought the module specifically because my truck shifted hard in any throttle position being tuned. Well I read a review or two saying the stealth module resolved that issue even thoe stealth doesn't make that specific claim on their website. Well 2 thumbs up! Turbo lag is about nonexistent and my truck shifts like a dream immediately after installation.Im a happy camper. Cant speak on any fuel economy improvements yet due to just installing.Well worth the money on my opinion.
I bought the stealth module for my 2014 F250 6.7 power stroke. I was getting around 12.5 to 13.5 mpg with lift tires and heavy duty bumpers. This thing brought me back up to about 17 to 20 mpg depending on my foot. After a year or so I noticed one day I was back to 12.5 to 13.5 mpg so I called them just to see what they’d say. I thought maybe it’s the module or I had something else going on I was unaware of. I explained to the technical support person that I wasn’t exactly sure what could be going on with my truck to loose the fuel mileage but that I had no codes and everything seemed to be ok with my truck other than the fuel mileage. He told me to contact warranty department and go from there. A brief questionnaire later and I thought well that was simple and easy enough. Yep couldn’t ask for a better warranty/product/support. I literally received an email with a shipping label to return mine and a tracking number for the replacement they’re sending me. If there’s anything they have that I would use I will definitely get it thru them. Thank you Stealth Performance Products
