Whether you’re looking to add just a little more power or a completely different turbo, the 6.7 Cummins-powered Rams have a ton of potential.

It’s no secret that diesel truck enthusiasts are always up for more power, and the current market definitely reflects that fact. There are hundreds of power upgrades for the later 6.7 Cummins, which are still some of the best diesels on the market. They’re still a little behind Ford and GM in the horsepower wars however, so we’ve selected some products that can add power and performance to your truck without breaking the bank. These performance parts are also completely emissions-friendly too (California compliance is still pending in some cases) but all will help your Ram catch up to those pesky Duramaxes and Powerstrokes!

EZ Tuning For The 6.7 Cummins

The smartphone has literally changed the way we live. So it should come as no surprise that yep, you can now tune your truck with one. This technology comes from Edge Products, a company that has been a leader in the diesel industry for decades. Not one to rest on its laurels, Edge has evolved into one of the leaders of emissions-compliant tuning, that can still add a good amount of power to your diesel pickup with the EZX Module.

The Edge EZX is a highly featured tuner that you can use to adjust power levels and more directly from your smartphone.

Edge was able to safely extract another 60 horsepower out of the 6.7 Cummins while helping it deliver more than 1,000 lb-ft of torque. This means the Ram can now crank out more power than a stock GM, and gets even closer to the Ford. Power is only part of what the EZX does, however, as many of its features are the most requested items of diesel truck owners. There’s a tire-pressure monitoring adjustment, speedometer correction, turbo timer, customized throttle response, and much more. Oh yeah, and you can adjust it all through your phone.

We added one to a 6.7-powered Ram and it cut a huge amount of time off of our 0-60mph time. The truck went from 8.4 seconds to 7.7 seconds. This same advantage extended through the quarter mile, as the Ram’s stock 16.4 at 84 mph time and speed was eclipsed by a time of 15.6 seconds at 89 mph. Ok, so it’s not a rocket ship, but that’s still a pretty big difference.

The Edge is 49-state legal (California certification is pending) and yet is still able to add a meaningful amount of power. In our book, the new EZX is a solid win.

Taking Your 6.7 Cummins To The Banks

Banks has been known for decades for their power upgrades, and its Monster Ram intake horn features a ton of extra flow, and is completely emissions compliant.

The next item on our list of 6.7 Cummins upgrades is Banks Power’s Monster-Ram Intake System. This intake manifold offers more than double the airflow of the factory intake horn, which is just about the most restrictive part of the intake system. Banks notes, “Your Cummins engine consumes a massive amount of air and struggles to breathe through its tiny, squashed inlet. The stock horn causes boost loss at the same flow while the Banks Monster-Ram has a wide, unrestricted, free-flowing path.”

Adding the Banks’ Monster Ram not only leads to more power, but better turbo longevity, and quicker spooling. The Banks intake also has four 1/8-inch NPT ports for sensors, or to make room for off-highway modifications like water-methanol or nitrous oxide injection. There’s also a provision if you want to remove the factory grid heater and add Banks’ improved design that erases the chance of the heater grid bolt falling into your engine. Users reported a smoother and quicker ramp into power (peak boost was achieved 200 rpm sooner in previous Diesel Army testing) which of course equates to a slight bump in torque. If you’re looking for aesthetics, torque, and added safety for your engine, Banks has it.

Compounding Those Turbos

DPS offers a compound turbo kit for the 6.7 Cummins that retains all of its factory hardware. Extra power, more boost, and cooler exhaust gas temperatures are all benefits of a compound turbo system.

Diesel Power Source (DPS) is proud to announce the availability of an emissions-friendly, add a turbo kit for 6.7 Cummins. This is a compound turbo upgrade that utilizes the stock turbo and adds an S475 turbo (larger turbos are available). Adding a second turbo offers serious help with towing, lowering EGTs, and a definite boost in power — all while (according to DPS), being emissions-friendly. The DPS 6.7 Cummins twin turbo kit uses the stock turbo and works with or without factory emissions. The EGR, DPF, and exhaust brake can remain intact if desired.

The Diesel Power Source Add A Turbo Kit for 6.7 Cummins includes everything you need for installation. This is a direct bolt-on compound turbo kit with no fabrication required and includes a two-piece 4-inch downpipe to clamp to the factory exhaust and a high-flow air filter.

DPS claims horsepower and torque are increased throughout the entire RPM band, and are significantly increased in the mid and upper range. Typical increases in horsepower of 22 to 26 percent are expected.

When utilizing the stock turbo, the addition of the twin-turbo kit is specifically designed for engines making up to 600 horsepower. If going beyond 600 horsepower, DPS recommends using the S480 turbo, which is good to 700 horsepower.

**Note:  While this kit is completely emissions-friendly and can keep all emissions intact, as of this writing, DPS is still seeking CARB certification and does not yet have a CARB exemption.

Colder Air For The Cummins

Getting plenty of clean cool air into the engine is a big first step to performance, and S&B offers a complete intake system for all new Ram trucks.

The S&B Filters cold-air intake system for the fourth-gen Ram takes the principles and design of the 2013 through 2018 Ram’s factory Active Air and improves upon the entire system by combining the benefits of the Active Air with the size and available air volume that S&B is known for. Uses the same motor that drives Ram Active Air to activate its swing gate, giving you all the benefits of the stock system, plus much more. Draws air from the wheel well inlet under normal driving conditions or inclement weather conditions (ice, snow, rain) to protect against the elements.

In extreme heat, high loads, or high altitudes, the swing gate pivots when your truck accelerates to full throttle, opening the ram-air duct mounted behind the front grille and exposing cooler and less restrictive air to your engine.

Testing shows that the ram-air inlet opens when outside temperatures are greater than 91 degrees Fahrenheit and the truck is at full throttle. The ram-air inlet stays open for approximately three to five miles or until the truck slows to around 5 mph. This process repeats itself. Ram-air activity varies with your driving conditions.

Cummins Cheetah

The Fleece Cheetah is a turbo that’s just like stock, only better. Power levels of up to 700 horsepower are possible with the Cheetah turbo.

If you want to amplify your driving experience, a Fleece Performance VGT Cheetah Turbocharger might be the answer for you. Featuring a Fleece Performance exclusive 63 mm billet compressor wheel and a high-flow turbine wheel, this turbo is capable of supporting 700 rear wheel horsepower without sacrificing any drivability. As a 100-percent drop-in replacement turbo, the Fleece VGT Cheetah does not require any expensive kit or specialized tuning, just bolt it on and go.

The Fleece Cheetah features a larger 63mm FMW compressor wheel and Inconel turbine wheel to get more air in and out, and do it quicker than the stock turbo. In doing so, it will generate increased levels of boost for more power and cooler temperatures. Beyond the ease of installation, you get to maintain the full functionality of your stock exhaust brake, and all turbos feature a new actuator.

Adding emissions-friendly power to the 6.7 Cummins has never been easier and we look forward to seeing what else the aftermarket continues to deliver.
