"Stealth has increased my throttle response and eliminated turbo lag! I noticed a increase in horsepower and a little increase in fuel mileage" - Jason K
Thank you for submitting a review!
Your input is very much appreciated. Share it with your friends so they can enjoy it too!
Purchased with sceptical hope! It has far exceeded my hopes! No lag time just jumps out of hole with a lot of power, drove from Marysville Washington to Denver ,utah,Idaho and home lots of power! Well worth every penny!
Not driving very much due to the price of fuel. But have seen a 8 mpg increase in fuel mileage. Have gone from 15 to 23 mpg so far I'm very pleased with the Stealth Performance box and have recommended it to my friends
I pull a 34ft 5th wheel camper and the fuel milage has increased by 2.5 mpg and even with all the emissions stuff on it running on the HWY I've gotten 20 mpg at a steady 72 mph. When I bought the truck it got 6.75 pulling the camper home from point of purchase and 16 mpg on the highway. So much improved fuel efficiency. Drawback, harder to install than advertised but still worth it.
I installed this on my truck. I have it stacked with my Shorty Jr. and deleted and I absolutely love how much it changed the driving experience in my truck. I have went from averaging 16 to 17 on the highway to 18 to 20 mpg. I love the feel of the low end power you feel and no lag.
Runs much better no more throttle lag, and picked up 2 more mpg, the stock 12 is a gutless pig, Ram hit this model with emissions that severely slowed the response down like its super restricted, well now it’s not!!!! Pretty easy install with some mechanical ability, I was a bit hesitant with the shims but that was easy, the harness plug is the tough one!! But it comes off easy after moving a few items, thanks Stealth you guys rock!!! I run the selector switch on low pulling 20,000 lb fifth wheel.
As described!! Very satisfied with the Stealth product. Much improved throttle response and so far 2+ increase in mpg! Thanks for taking my call on a Sunday! That’s great service!!
Did the shim kit and the Stealth controller. Throttle response is 100% better. Less throttle to move the truck. Haven’t had it on long enough for fuel mileage but I think it will be close to 3 miles pr gallon. Depends on your driving style really.
Really impressed with this module. My truck is deleted with 200k miles and was looking for something for everyday driving with better throttle response. Does great on the low end when you go to pass someone and it definitely builds boost quicker. I would definitely buy it again.
Bought my stealth performance products module (selectable module) back in October for my 2011 Cummins. Installed it before I made an 1800 mile trip from Arkansas to Colorado while towing a 34ft camper trailer. Needless to say there was a difference in power and some fuel economy benefits. Previous year I averaged 8 mpg (hand calculated) and struggled with the winds in Eastern New Mexico. This year i was sitting anywhere around 9-11.5 mpg (hand calculated) and had no dead pedal or power loss. On the drive back my truck was empty so I ran the module on high while on I40, the whole way back I was up around 22mpg. One of the best choices I've made for this truck was buying one of these modules for my Cummins. Worth the money!
This is my first 6.7 cummins, I have had about 10 of the 5.9s from various yrs from 12v to 24v to commen rails With great success and great milage.. I don't tow real heavy but 6-9k, This truck is an 08 4wd, 3500 ram SRW rolling on 35" toyos, had ample power but fuel milage ******, towing 11-13 mpg, with relatively no wind resistance, empty around town about the same, empty down the highway a conservative 16mpg, So I did some research I was looking for some additional fuel milage, not so much power, I didn't want to do the DPG and EGR delete, didn't want to be forced to put gauges etc in truck, and I came across this Stealth programmer.. It has been the best and most simple way to achieve what I was looking for, and WOW did it wake the trucks performance up !! At present these are my milage increases, done by pencil and paper, not going off of the EVIC, close to 14.5 towing and it doesn't slow down in the hills, almost 17.3 around town, and tickles the 20 mpg on the highway empty, I'm very impressed with the results.. Thank You Stealth Products, I believe It has achieved more than I expected.. fairly simple to install, for some, shimming the fuel rail relief plug maybe a little daunting, but pretty straight forward, I'm a 65 yr old man and have to admit for me to get in to some if the areas designed for people that have smaller hands was kind of comical.. I feel for the average person it's a total of 30 minutes for the complete install, but we'll worth it !! Thier Customer service is outstanding as well as the product.. Thanks FOR THE GREAT PRODUCT !!
This is one of my favorite products it’s safe on the motor no worries about stretching head bolts or blowing head gaskets it leaves all the stock safety parameters in place and works as advertised. The only thing I had to do is shim my fuel rail witch only took about 40 minutes. Also I would like to thank Wyatt for all his help he was Jonny on the spot when ever I needed some questions answered.
at first I was skeptical...oh it's just another tuner...oh it will do something tamd the dealer will find out. I bet if I call these people ill get a hotline to india.......nope. dude that's owns the MF answered the phone on the second ring. answered every question I had. although still I was very skeptical. his statement of...."I answered the phone man, if these things had issues, I probably wouldn't have answered" this got me hooked...so I ordered it....only issue I had was NOT reading the instructions and out a plug on backwards and the truck barely ran, read the instructions, put everything back where it was supposed to be and how it was supposed to be installed, never looked back, I went from 10-12mpg to Right about 15mpg. out of all the settings on the switch I keep it in the middle, more than enough for what I'm trying to accomplish. best part is. easy to remove and the dealership has no idea. love this thing.
Very impressed with the switchable features. The 90 extra HP will set you back in the seat. The paper work says be careful not to lose the pin in the fuel pressure cap however there is not one in the 2012 6.7L. The only thing I would ask for is more threads on the switch so it will be able to go through a thicker area. Other then that very minor thing I am very glad I spent the money on the stealth product.
Install the stealth module a month ago .. Fast shipping tech support almost 24 / 7 . Once installed I noticed a big difference !!! Pedal response no turbo lag it helped me out big time pulling my 26ft toy hauler thank you for this awesome module !!!!
