- Turbo lag
- fuel mileage
2019 f350 king ranch
My fuel mileage has went up by about 2 miles. And much better take off.
2015 Ford F-250
No more turbo lag. Haven’t seen much in the way of better fuel economy, but would definitely recommend purchasing!
Ford F-250 Platinum 6.7 Diesel
After upgrading wheels and tires to 37"s, truck didn't pull like I had wanted. Added the Stealth module and instant improvement. Not sure whats going on inside that little box, but it is worth it in terms of performance! Well done.
Damn good customer service
I had an Issue with the module that I had purchased. Called for troubleshooting tips. The guy I spoke with was very knowledgeable and very helpful and fixed the issue very fast and now have the new parts on there way and could not be more pleased not only with the product but with how this company handles their customers service. I would buy from them again in a heartbeat!
2019 Ford F-250
I like a lot of people thought the product was too good to be true due to all of the great comments about it. I ended up buying one 3 weeks ago to try it out and love it. It took about 3 days of running it on the medium setting to see a difference. Turbo lag was cut in half the truck will really get up and go. I noticed a 2mpg increase on the interstate rolling 75-80 on cruise I’m getting right at 18.5mpg. Took it too the dealership To have maintenance done took the stealth off before I got to the shop fixed what I needed under warranty never asked a question.
2016 Ford f-350
Easy to install if you have small hands, had to have my wife do the connection's. Went from 9.5 mpg to 11.5.didnt feel much power gain, but bought the module for millage anyway. Would definitely recommend
I'm really happy with I have it combined with a pedal commander wow is all I can say.
2014 F350 Platinum
Awesome increase in fuel milage and throttle response.
2017 ford F250
Had to buy new tires had 50k miles. They just couldn’t handle the power
2018 ford f-250
Towed my 32 foot trailer without the stealth module. She was ok but had that dead pedal feel. Ordered my module and felt like it was a different truck. I’m very happy with my truck now
2015 CCSB Lariat Power Stroke
My experience has been great. Had the module on since I bought the truck about 9,000 miles ago. Noticeable power bump as well as fuel mileage. Love it, will continue to run it.
2018 F250 Platinum
Easy install, huge difference in power. I combined it with a pedal commander I already had and it’s like it’s tuned! Up 3mpg’s after 2.5 months of use (and after I quit flooring it at every light or on ramp). Great product
I’ve been running a stealth on my ‘17 powerstroke since they were first released. The modules have always helped my truck tremendously with fuel mileage, throttle response and lag but this newest version of the module that I received on 07/19 is amazing! Has a very nice bump in power that you can feel and Ive picked up 4mpg cruising along at 75mph. I drive a crew cab with w 9ft utility bed that’s usually around 12.5k pounds so I can use all the help I can get to get this heavy pig moving not to mention I put on 1k+ miles a week so the increase in fuel mileage alone makes it a no brainer, module pays for it self in a couple weeks just in fuel savings alone! Eric, Krista and the whole stealth team has been very helpful and quick to resolve any issues I’ve had over the last 2-3 years. Definitely a product I’d recommend!
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.
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.
