How Do Diesel Tuners work?

The best tuner for stock 6.7 Cummins allows you to adjust the engine for a specific function. You can use it to optimize performance and increase fuel efficiency. There are many more options today than ever before, providing a complete selection of 6.7 Cummins tuner models to the market. Keep in mind, it’s not necessary to have a Cummins tuner, but it does allow you to make adjustments to your engine.


Benefits of Tuners & Programmers For Ram Trucks

The best diesel tuner for 6.7 Cummins helps you achieve more torque and power from your truck. It also produces a smoother ride while improving the fuel economy. Most people use the tuner to increase horsepower, but there are other purposes. You can purchase tuners specifically for fuel economy, higher torque, and increased throttle response. 


How To Choose The Right 6.7 Cummins Tuner

Compatibility

Obviously, it doesn’t make sense to purchase a tuner that isn’t meant to work with your 6.7 Cummins diesel engine. Instead, this is the first criteria for finding a reliable tuner for your truck. Search for available parts based on the truck model and year you drive. Don’t worry; there will still be plenty of options for your Ram pickup.

Ease of Set-Up & Use

Unless you are an expert, you probably don't want to deal with a complicated setup. Reach through the tuner customer reviews to find out how simple installation was. You will also need to make a note of any additional tools or skills you would need to complete the install. The same goes for the operation. Don’t choose something that will be overcomplicated to tune.

Power Levels

How much power are you hoping to receive from the tuner? You should know this in advance before choosing a model. As you will see in our best tuner reviews, each model comes with a specified amount of power tweaking. If you are looking strictly for additional power, then it won’t be hard to find a reliable model.

Storage

How many tunes will the programmer hold at one time? It’s important to evaluate this if you plan on having multiple programs saved. This allows you to change the programming for a different application without having to re-enter all of the information again. The advanced tuners come with the ability to hold several tunes.

Monitor Size

If you want to be able to see the tuner with ease, it makes sense to choose a larger monitor size. However, some people prefer a smaller and compact monitor that will remain out of the way. Determine what area you have to dedicate to the monitor to find the size that works best for you.

Versatility

If you want the option to change the performance often or continue to customize it until you find what you want, it helps to look for models that allow for additional adjustability. Remember, any extra features you have will increase the price, but also make it easier to use. It’s a trade-off between capability and expense.

Design & Style

How do you want the programmer to look? With the best programmer for 24v Cummins, you will find an easy-to-use design that also reflects your style. After all, you take great pride in how your Ram pickup truck looks. There’s no reason to sacrifice that just to increase the performance and tweak the engine.

This Smarty Tuner 6.7 Cummins model provides versatile functions for your Ram truck. It works on trucks from 2007 through 2012. If you want to use it on a new truck, you will need the additional COM module to make that happen. Choose from ten power levels, including one that will reduce the horsepower. You can achieve up to 170 horsepower, depending on how you configure it. Because it contains a twin CPU, you can expect speedy uploads, plus you can save functions on a microSD card.

We like the larger 4.3-inch display that showcases four dashboards and five gauges. You can even customize the background. Ram truck owners from years gone past can’t say enough good about this model. Plus, the price isn’t unreasonable at all, considering how much power you can achieve with some simple programming.

We don’t like the one-year warranty and would have liked to see a longer-term for this kind of money, but we understand working with engine modification is a tricky business. Considering it's not easy to find a programmer with this much control, we have to recommend it. Use it to improve engine performance, extend braking life, and engineer your Ram to be precisely what you've always hoped for.

Pros

  • Plenty of customization
  • Up to 170 horsepower gain
  • Large, customizable display
  • Works on older Ram trucks

What sets this highly-rated Raceme Ultra Programmer apart from the rest is the EGT Probe Pyro Kit that comes with it. You can use this for the 2007-2017 Dodge Ram 6.7 Cummins Diesel 6.7L truck models. This tool will monitor the engine and powertrain parameters to ensure maximum optimization.

What we really like is the Exhaust Gas Temperature (EGT) monitoring that doesn’t come with many of the other units. To set this up, you will need an external sensor instead of simply connecting it with the OBDII port. Not everyone wants to put forth this additional effort, but it’s worth it.

Expect some of the same functions as the other units, such as programmable tuning options and a handy screen that makes operation simple. What is different is the price. Because of the additional capability, you can expect to pay much more to install this in your truck. However, customer reviews suggest that you won't want anything else.

We recommend this as the best tuner for 2013 6.7 Cummins, among several other years. You can increase performance, upgrade the torque, and watch your fuel economy with ease. Just install it and watch all the ways this machine will increase the efforts of your Ram pickup.

Pros

  • Lots of customizable options
  • Monitors EGT

  • Works on many Ram truck models

Cons

  • Expensive
  • Requires additional sensor setup

This Edge tuner 6.7 Cummins model works perfectly with the 2013-2018 6.7L Cummins. It’s regularly rated as an exceptional 2015 6.7 Cummins tuner, among other years.

The five-inch monitor keeps track of the performance, while the controller allows you to make quick adjustments, even while moving. You can adjust between increments up to 150 horsepower and 350 pound-feet of torque, depending on what model you drive. You can also put the truck back to the stock tune if you need to. This tuner even features some safety functions, such as a turbo timer, backdowns, and cold-engine protection.

We love the slim and sleek design with a customizable background. The high-resolution screen also features full color. Sadly, there are no tunes for deletes. While the price is reasonable, we were surprised to see it only comes with a one-year warranty. Reading through the Edge customer reviews gives us additional peace of mind that this model is worthy of the cost. It won’t just stand up to the test of time but offers superior optimization. Get more power out of your Ram truck with the help of Edge.

We enjoy this Edge tuner for use with a 2003-2012 Cummins, but it’s not the only truck it is compatible with. You can also use it on a 2001-2016 GM Duramax or 1994-2019 Ford PowerStroke. Few programmers can claim that much capability. By reprogramming the stock computer, you gain access to so much more power. You simply place this in the cab for simple control.

It hooks into the OBDII port, so you don’t need any expertise to get started. It will also save the stock files in case you ever need to revert back. The real-time monitoring allows you to watch engine data for exceptional diagnostics. The five-inch color display is simple to see and customize to fit your needs. Use it while you adjust up to an additional 180 horsepower and 440 lb-ft of torque. With the slim, sleek case design, you might forget that it’s even installed.

The price is not unreasonable by any stretch of the imagination. Even the reviews back up the reasons why this is one of the best tuner options for your Ram truck. It works perfectly with the 6.7L Cummins and is sure to bring out the power you never knew existed. The only trouble is the one-year warranty, which is slightly low in this industry, but we can’t ditch this model over that technicality.

Pros

  • Large, easy to use screen
  • Many power levels
  • Retains stock information
  • Rave reviews

Cons

  • No deletes

Engine Tuner Compatibility

You can’t expect all engine tuners to work on every year and model. Instead, you want to look for a tuner that’s specifically designed for your year Ram truck complete with a 6.7-liter Cummins engine. Each manufacturer clearly lists what years and models the tuner is meant to work with. If you attempt to use a tuner not meant for your engine, you won’t receive the programming you need. Don’t even purchase one meant to work on a Cummins engine from another year.


Installing a 6.7 Cummins Engine Programmer

Every engine tuner is going to have its own instructions for installation. For the most part, it will follow these basic steps.

  1. 1
    Remove the tuner from the box. Make sure all of the components are included.
  2. 2
    Plug the performance tuner into your OBD-II port.
  3. 3
    Follow the tuning instructions given to you from the manufacturer.
  4. 4
    Enjoy the ride.
