What’s the Best Tuner for 6.7 Cummins? Reviewed, Best by Model & FAQs

1. Edge Products Juice w/Attitude CTS2 – 31507 – the best tuner for 6.7 Cummins

No products found.

The Edge Products 31507 is a combination of a monitor (that displays your trucks performance and various other parameters) and an in-cabin controller for the Juice module. It allows shift-on-the-fly power tunes, accessed with the help of a touch screen monitor. Very handy!

Made for 2013-2018 6.7 Cummins Ram 2500/3500 trucks, the tuner offers increments of up to 150 hp and 350 lb-ft, depending on your truck’s model. There are five tunes that can be accessed on the go, whereas a sixth one requires an additional unlocking fee.

Edge Products claims that the tuner comes with an ability to go back to the stock/factory tune on demand. But on using the pre-defined power levels, there’s bound to be an improvement in the truck’s low-end grunt, and the tuner also doesn’t miss out on safety features like cold-engine protection, backdowns, turbo timer, etc.

The Attitude CTS2 monitor bundled in Edge’s tuner kit is feature-packed. The high-resolution display gets an HDMI-style plug for hooking up accessories and EAS. It has five swipe screens, an ability to auto-dim when the ambient light goes down (like at night), customizable backgrounds, needle styles, and screen layouts. And if that wasn’t enough, the kit can be updated using the internet. That ensures that not only is your truck more powerful, it’s also made to run with the latest tuning software as well.

No tunes for deletes

While the tuner itself is legal for use in 50 states and also comes with a CARB exemption, Edge Products maintains that the tuner doesn’t support deletes. But the device itself supports ECU unlocks, so if you have deleted your 6.7 Cummins and have access to a custom tune, you can still use it. Our suggestion is to get in touch with Edge Products for more clarity on this.

What do we think of it?

If you’re looking for the best diesel tuner for 6.7 Cummins in all-round performance, the Edge Products Juice with Attitude can be a good purchase. The only limitation is that it doesn’t allow deletes, but with a variety of maps — and the ability to go back to stock form — makes it unmissable.



  • Tremendous Power Gains
  • High-res monitor
  • Shift on the fly
  • CARB exempt


  • Doesn’t allow deletes


2. Smarty Tuners 98.5+ Touch Tuner

No products found.

Another combination device on the list, the Smarty Tuners 98.5 Touch Tuner. This Smarty Touch programmer is available for both 6.7 and the model that preceded it, the 5.9. Compatibility for the 6.7 is from model year 2007.5 onwards to 2012. If you have a truck that’s made after that, you’ll additionally need to purchase a COM module. 

There are 10 power levels to choose from, including one for reduced power. The maximum power gain that can be achieved with the Smarty Tuner, according to the brand, is 170 hp. But it’s not just the power boost that gets people talking about the programmer.

Speed limiter and power on demand

It boasts a variety of features like a twin CPU so that the monitor and the module both have individual processing power. It also can be upgraded via the internet, comes with the ability to save multiple tunes on a microSD card, has a programmable limiter for speed, and on the older trucks (2007-2009 6.7 Cummins), there’s a power-on-demand feature as well.

The monitor is a 4.3-inch display, which offers four dashboards with five different gauges. The display background can be customized, and it claims to be the fastest display in the industry, among other things. While you can monitor EGT with the help of an optional probe fitment, the diesel tuner is set to work with DPF in place.

What do we think of it?

Connect this to your truck’s OBD-II port and you’re good to go. Smarty Tuners offers a wide variety of power levels and a variety of features. Also, if you happen to own the earlier 5.9 Cummins truck, this makes for a good choice.



  • Massive power gains
  • Twin CPU
  • Power on demand on earlier trucks


  • Newer RAM trucks require an additional COM module
  • Not for sale in California

That’s the RaceME Ultra Tuner’s strong point. Compatible with 2007.5 – 2018 6.7 Cummins trucks, the tuner by RaceME is made only for off-road/competition purposes.

Massive power gains and delete support

The key features that make this the best delete tuner for 6.7 cummins include an ability to extract up to an extra 200 hp, clear error codes, and even disable EGR and DPF. Although the brand recommends hard part removal in the case of EGR.

The monitor comes with multi-gauge layouts, and the onboard software can be updated with the help of a microSD card — it gets monthly free updates. The diesel tuner also helps recalibrate the speedometer (in case you’re using non-stock tires on the truck), comes with TPMS, and even offers customizable injection timing for desired performance/economy gains.

Most importantly, if you’re just looking for a tuner to run with your deleted truck, then the RaceME fits the bill perfectly. It offers power increments in a total of five stages, and the first stage (Stage 0) is to run on stock power but with EGR/DPF delete.

What do we think about it?

Not only a lot of features/custom tuning possibilities, but the RaceME Ultra also gives you the choice of running your deleted 6.7 Cummins Ram 2500/3500 on stock power. And it doesn’t skimp on basic features like speed limiter, either. It’s a bit expensive, though. Is it a great tuner? Yes.

  • No Highway use

4. Superchips Flashpaq F5 Tuner

No products found.

If you’re not convinced with the idea of mounting a larger touch screen to keep an eye on your truck’s performance or if you’re just looking for a simpler solution, the Superchips Flashpaq Tuner promises to do the job well. It’s a handheld tuner, compatible with 6.7 Cummins Ram 2500/3500 trucks (model year 2007 – 2010), that connects to the OBD port of your truck, and essentially does everything that you’d want with a mid-tier product.

What do we think of it?

At a fraction of the cost of other tuners, the Superchips tuner offers a list of useful features. If you’re looking at a simpler alternative to full-fledged tuner setups, this can be a good choice.

Note: While Superchips mentions that the tuner is 50-state legal, do check with the seller regarding its compatibility with your truck and the corresponding CARB status.

  • Handheld so no separate monitor
  • Power gains aren’t huge

5. Edge Products Insight CTS2 – 84130

No products found.

Investing in a monitor can be a good idea for a number of reasons: if you’ve modified your truck and want to keep an eye on how it performs in real-time, if you want to keep it stock for now but are looking at lateral upgrades, or if you’ve already upgraded and just need a display to track the performance gains. This Edge Products Insight monitor is a choice you will not regret.


The Insight depends on the OBD-II port to connect with your truck and HDMI-style plug for power and hooking up EAS accessories. With fully customizable backgrounds, a one-touch menu, notification center, and multiple-gauge screen layouts, the monitor is compatible with other tuning devices.

What do we think of it?

Instead of installing a plethora of analog gauges or depending entirely on your smartphone apps for readouts, the Insight GTS2 can prove to be a more intelligent upgrade. It’s not cheap, but it can be a life-saver.



  • Feature-rich
  • Easy to connect


  • Not a tuner per se

Our Final Thoughts

Like other forms of modification, tuning also requires some restraint. It’s tempting to go all-out on the settings, but you need to keep in mind that with the increase in power, there will be an additional strain on internal engine components and running gear. The same can be said about fuel economy if you set it up incorrectly and while the 6.7 Cummins diesel has maintained a strong reliability record, it’s a good idea to seek professional advice before custom tuning. So just keep that in mind while you’re tuning/choosing a tuner for 6.7 Cummins Ram 2500/3500. That’s an issue you’re less likely to face if you’re upgrading other relevant components as well.

If you’re looking at keeping track of how your truck performs, the Edge Products Insight is a great choice. Since it’s also compatible with other tuners, you can look at it as an investment, should you plan to upgrade your truck in the future. The Superchips Flashpaq is a no-nonsense handheld tuner that does its job well and doesn’t occupy too much space in the cabin, given its form factor. The combination kits (Edge Products Juice and Smarty Tuners) both offer a great entry point into the world of tuning. The RaceME Ultra takes it to a different level, with support for EGR and DPF delete. With an ability to extract an extra 200 hp, it can be an easy favorite for those looking at outright power gains.
