Make your diesel have more efficient power and fun to drive with our Ram Eco-Diesel 3.0L Stealth Module exclusively for Ram Eco-Diesel years 2014-2019. 

These eco diesel powerplants are capable platforms with great pulling power. The biggest complaint is the initial lag and low end power. These modules will solve that problem by not only improving low end power but also addressing the lag in the throttle signal.

Up until now these two factors were taken care of with two separate products. By combining them into one you can now get the performance you need out of one single device.

Your module will be a stand-alone computer that simply plugs in under the hood of your truck. It will not increase fuel volume, so there’s no need for any other modifications. Make your truck work smarter, not harder! Get that extra boost in performance without any harmful side effects.

Works with:

  • Ram Eco-Diesel years: 2014, 2015, 2016, 2017, 2018, 2019

The Ram Eco-Diesel 3.0L Stealth Module provides: 

  • Increased hp
  • Better throttle response
  • Brings your power curve down to where you need it most
  • Built-in throttle booster that brings the truck to life
  • Plug and play OEM style connectors
  • Stealthy technology that will not leave a footprint in your truck's computer - must remove the module prior to having service
  • Does not increase maximum rail pressure beyond stock parameters
  • No increase in exhaust temperatures
  • Includes a selector switch with 4 modes (stock, low, medium, and high) to manually adjust the potential of the module.

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 spectrum, 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.


  • The selectable module includes a switch with 4 modes:
    Stock, Low, Medium, and High

Why sacrifice peace of mind when looking for a little bump in performance?  No endless modifications or flashes to your trucks computer.  This is the easiest and safest way to give your truck improved performance.  A cost-effective approach to wake your truck up starts here.  Backed by a limited lifetime warranty, includes 24/7 technical support, and superior customer service.  Finally a high-quality, safe, and non-invasive performance solution your truck has been waiting for.  See why thousands of diesel pickup owners are turning to Stealth.

Mileage is impossible to guarantee with any modifications. Anyone that claims otherwise you should be very leery of. The majority of Stealth Equipped vehicles do see a mileage increase due to using the efficient low-end power our module provides to keep their RPMs down and hold higher gears. With responsible driving habits it's not uncommon to see a nice bump in MPG along with an all-around better driving experience. You're welcome to reach out to us so we can provide you with any tips we have learned from first-hand experience and speaking to tens of thousands of diesel owners.

    15 Ram EcoDiesel

    I was first a little skeptical. A stand alone with one plug and computer... Well curiosity got the best of me so I ordered one. Install was about 20 min. The difference was immediately noticeable. Mileage has went up about 1.75mpg on the highest setting. Going to try the other settings and will update the review if I can. The torque and the speed has increased more then what I figured I would notice. When getting on the highway the on ramps are now too long. Towing is great also. Stealth you guys have done a great job on this one. Would highly recommend their products.

    Great Tune!

    Customer service is awesome! Honored my request and very quick order processing. I have a mostly stock 2015 Ram Ecodiesel with a cold air intake, ECU tune, and the Stealth tune. Needless to say I have run within a hood length of a 6.7 Cummins, H&S tuned on Performance mode in an 1/8th mile drag!! Just Lovely!! :) On top end at highway speeds against the Cummins the governor kills it. I run this in stock mode 90% of the time. Great to have as the extra kick to put em in their place! I modify commercial vehicles adding aftermarket parts and this is high quality product. The knob is solid w/ a metal nut and the wiring is braided. No flaws yet! I would buy this again and highly recommend it. And yes for the Ecodiesel its a PITA to install the connector!

    2015 Ram Ecodiesel

    I ordered a module for my 2015 Ram Ecodiesel. The module arrived promptly. Directions were simple. Customer service A++ with fast responses. Unit is installed. First drive and initial impression is the module does what's advertised.

    3.0 ecodiesel

    Great product!!. Bought the module for the 3.0 ecodiesel, as soon as I installed it I noticed the pedal lag was gone. Even my wife noticed it while driving the truck. I have not driven the truck much to see if my mpg's have benefited, but regardless its a great product.
