SUPER HAPPY WITH MY STEALTH

[Jrsweet16]

wzup fellas i just got my dr performance module for my 16 2500 6.7l. iv had it for 250 miles of city driving and my needle is just about to touch half tank when i was barly seeing 210 MAYBE. I have noticed my trucks torq and obviously HP, but i purchased this thing for my MPG's. I was super spectical bout this thing improving and reading ur guys txts and inputs, and i really have to say all u guys against it UR WRONG, this thing works. thats all i have to say bout that fellas, check it out Dr performance rx .com
$600 for def trucks
$550 for non def trucks

When you fill the tank to the TOP (as in dripping from the overflow) at the same location 3 times in a row. Report what your actual hand calculated mileage is.

Just so you know you have just voided your warranty, yes they can tell you had something on there.

NO Dr Performance is NOT going to defend you in court when U are trying to use the Magnuson ACT.

But hey if you are happy that's great.

I wonder how long they will be around before the EPA takes them out.

Ok here it is hand calculated 95% city driving stealth module
Tank #1-338.5 miles filled up with 19.238
= 17.5953841, for all you technical punks
Everyone else 17.6
I will let you all know tank 2 when i get there its not an everyday truck so bare with me fellas, i dont baby the truck like i used to, if you all read my other posts i posted, i had to baby this truck like 1yr old kid with diapers full of crap, but not any more i drive normal now thank god, i was bout trade it in for my 6.2l gasser.

Glad you found a solution that works for YOU. That's what it's really all about.

Anywhere near 17mpg with that much city driving I'd consider a win. I recently took my first solo trip with my 14, completely unloaded there and very lightly loaded on the return. Aerodynamics played a larger role than weight with the wood burner sticking up above the cab close to 12".

I fuel up at home and use a pump that does not have a counter. I filled up before leaving the driveway and took the picture of the trip meter after I pulled back into the driveway. Whole trip was done without refeuling. Low fuel light kicked on within a few miles of pulling in the drive. Just for comparison sake.

Jr, nice info man i will take pics as well and i will post them asap, it was really hard for me to buy this thing, i was afraid it wasnt gonna work n it was gonna be another tuner but no man, not this one, im very happy so far. Thks for the reply. My truck is 100% stock other than the stealth module tuner. '16 2500 6.7l crew cab short bed 4x4 factory luxary 20" wheels and factory firestone tires. Now i really like driving it.

Glad it’s working for you, I realy like my EFILive. It woke up my lazy C&C with 305HP and helped in mpg. EPA has choked off a lot programmers for them, glad I got my EFILive prior to them coming down hard on them. I’ll bet you can’t buy the Stealth in Comifornia though. I looked into getting a Stealth before I found out about EFILive, and was going to have it shipped to Vegas, until I found EFILive that I could get a multi tune with switch.

Question for you. Does the Stealth have different tunes, like one for towing, one for performance, and one for MPG?

Rvtrkn, yes it does it has 4 settings
Stock, low-30hp, medium-60hp, high-90+ hp and with it set at on the high setting it has 112lb ft of torque, and all this is Rear wheel gains, "so they say", but ift does move its a different truck its feels lighter, now i cruz on freeway 75-80 mph man and not think about it anymore as when i didnt have it, all i was thinking about was how small my wallet was getting at those speeds, ITS WOKED FOR ME AND I LOVE IT!!!!! Thank for the commenting, cheers

I purchased my Stealth Module last year to bring up my 2017 5500 C&C up to pickup HO Cummins numbers. I run mine on 60 HP setting. I keep a fuel log and have seen about a 0.6 mpg increase, but I bought mine for HP gains, which it does seamlessly. Interesting. Stealth isn't supposed to work on C&Cs, but it does on mine. And towing is great. Nice increase in lower end HP and TQ with no discernible increase in vehicle temps and get the slight mileage gain. Pretty nice in my book.

I had MADS Smartys on my three previous trucks, but could not get a response from them after two tries, so they lost a customer.

Glad you like yours, I certainly like mine.
