Stealth Module for diesel trucks

“Stealth” as in an illegal modification?

It must work as the answers are not visible.
Seriously what are you referring to?

Had to google it and found it's a performance module see test here.

Anything you need to hide from the manufacturer because it will void the warranted is probably not a good idea.

I don't think I have seen so much double speak in an article in a looooog time!

What dont you read Elon Musks tweets?

So it's a device designed to help you commit fraud.

Adjust the operating parameters of the engine but if you break something you can remove it and then go in for warranty repair.

Nice!

Where's the morals police?

LMAO, ok, ok, ok, Hone you got me there!

I have heard some good things about it on the Cummins forum. It is very similar to the Edge JWA module I ran for a short time, but at least with that you get a monitor as well. Unlike modules of the past that broke stuff left and right (especially when stacked), the modules today seem to be pretty mellow in their tuning. Generally the max hp gain with these modules is the lowest hp gain from a custom tune or flash.

The downside of these modules is that they generally increase soot levels which will increase regens. This may cause a slight drop in mpg depending on which setting you have it on. The other part I don't like about these modules is that they do not tune the transmission to handle the added power which is also why they are generally mellow on their performance gains. Any more power without a trans tune to increase line pressure, adjust TC lockup, and alter shift strategies and you are cutting into the longevity of your trans.

At the very least I would get a BD trans line pressure increase booster/fooler harness if you decide to go this route. This will fool your solenoids to output higher line pressure percentage then commanded keeping your clutches alive. Don't worry, it will not increase it to unsafe levels which is over 170 psi fir the 68RFE with a stock valve body.

The Cummins engine alone can reliably handle a lot more horsepower (as in hundreds more) than this module can supply so no need to worry there.

You’ll get all kinds of fun responses with this MRE.
Bottom line if you’re looking to tune the truck, Stealth is cheap cr@p. There are better tuners.
