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.

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
3. RaceME Ultra Tuner for RAM Truck 2500/3500 – the best tuner for 6.7 Cummins dpf delete

But what if you were looking for the a programmer that can accommodate DPF and EGR deletes on your truck? Or something that could make more power and offer an even wider array of features? 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. There’s also transmission tuning (non-Aisin gearboxes) available, in addition to real-time tuning, which can affect the timing, VGT (variable geometry turbocharger), etc.
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.
- Custom tuning possibilities are endless
- Wide compatibility
- No Highway use

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.
The 50-state-legal tuner offers the ability to adjust speed, rev limiter, shift points, shift firmness, etc. There’s also active fuel management control, and with this, you’ll also be able to read and clear diagnostic codes. The speedometer can also be corrected as well.
Multiple power modes
The tuner itself can be updated from the Internet using USB, and while it doesn’t have a full-fledged screen like the others here, this gets a 2.8-inch color screen with limited graphical user interface (it’s not a touch screen). The power levels available with this include economy, towing, daily driving, and extreme tuning.
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.
- Good features for the price
- 2-year powertrain warranty
- Handheld so no separate monitor
- Power gains aren’t huge

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.
OBD-II and HDMI
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.
It can be updated from the Internet, comes with 5 full-color, high-resolution swipe screens, and can also be programmed to make audio and visual alerts. The high-quality screen also lowers its brightness automatically making using it at night a strain-free experience.
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.
- 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.
Best 6.7 Cummins Tuner by Year (2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014 & 2015)
As it replaced the long-standing king of diesel engines from Cummins (the 5.9 Cummins), the 6.7 Cummins did face the huge task of winning the hearts of customers, both old and new. And so it did. It’s gained popularity and quickly became the diesel engine of choice for buyers. Among the choices for a new 6.7 Cummins tuner, we’d go for the Smarty Tuners 98.5 Touch Tuner. It’s got 10 power levels to choose from, comes replete with Power-on-Demand feature, and has a good 4.3-inch monitor as well.
It’s hard to not recommend the Superchips Flashpaq Tuner. Not only is it a powerhouse in a small form factor but also a good alternative to larger systems. At 2.8 inches, its screen might not display everything (like a larger monitor), but you can be sure that it’s easy to operate and not short on features. The handheld tuner comes with power levels like economy, towing, daily driving, and extreme tuning. You can access most features available on other tuners like the ability to adjust speed, rev limiter, shift points, shift firmness, etc.
If you’re looking for a tuner that accommodates deletes, then there’s a solid choice for the 2011 6.7 Cummins. The 6.7 Cummins came equipped with emissions-control equipment, and should you decide to remove those for off-road/competition purposes, this, the RaceME Ultra Programmer makes for a good buy. You can also clear engine codes, and there’s the option of real-time tuning as well. It comes equipped with a multi-gauge-layout monitor, so you’ll be able to know what your truck is doing in real-time.
There’s a possibility of gaining up to 170 bhp with the Smarty Tuners Touch Tuner, and the 2012 6.7 Cummins is likely to make the most of it — if you’re looking for a massive power increase. It comes with a 4.3-inch display that can help you keep an eye on how well your truck is performing. It has display backgrounds that can be customized. It comes with four dashboards with five different gauges, so there’s a lot of information on display. Like most others, it can be upgraded using the internet, and you can save multiple tunes/engine maps on a microSD card.
If you’re talking about the 2013+ 6.7 Cummins trucks, then it’s impossible to ignore the Edge Products Juice and Attitude CTS2. The CARB-exempt Juice tuner enables a power increment of up to 150 hp, and you can access its five tunes on the go (shift-on-the-fly is possible). Other features include the ability to go back to the stock tune. It also comes equipped with features like cold-engine protection as well. The high-quality Attitude CTS2 monitor takes things up a notch. It has an auto-dim feature that’s unbelievably helpful in the night, and a variety of customization options: backgrounds, needle styles, and even screen layouts.
For a competition/off-road truck, performance is everything. And with the RaceME Ultra Programmer, you can enjoy every bit of performance from your 6.7 Cummins truck without any worries at all. The programmer is made for trucks that have undergone deletes, and thus can only be used on the track but not on public highways. Depending on the model and the other upgrades, it can help you extract up to 200 hp, tune the gearbox and the turbocharger as well. It’s slightly on the expensive side, but with a long list of features and the fact that you can use it on a deleted truck, it’s worth it.
It’s easy to see why the Edge Products Juice and Attitude CTS2 combo works so well on newer 6.7 Cummins trucks including the 2015 model. You can monitor the truck’s performance in real-time, access and change power tunes on the go, and enjoy up to 150 hp of power increase. With an unlocking fee, you can also get a sixth power tune — the company offers five tunes unlocked on the device. The monitor complements the feature-loaded tuner and can also double up as a display for accessories and EAS.
