1. SCT X4 Performance Programmer – the best diesel tuner for 6.7 Powerstroke

SCT Performance - 7215 - X4 Performance Tuner - Custom Power Flash Programmer- 08-16 DCX
54 Reviews
SCT Performance - 7215 - X4 Performance Tuner - Custom Power Flash Programmer- 08-16 DCX
  • WIDE MODEL FIT - Fitting a wide array of Dodge (DCX) Models. Enter your vehicle above to verify compatibility.
  • VEHICLE DATA OVERLOAD - The X4 Power Flash makes it easy to read the real time vehicle data, view popular sensor data such as EGT, Air / Fuel Ratio or any other 0-5 Volt source!
  • READY TO GO - The X4 Power Flash arrives pre-loaded with DYNO proven tune files that increase Horsepower and Torque.
  • CUSTOM TUNING - Control your vehicle's performance fully with custom tune capability and an adjustable tune interface.
  • EASY UPDATES - Built-in Wifi allows you to easily attach to your local area wireless network to download device updates.

Made for a multitude of Ford products, the SCT X4 Performance Programmer doubles up as one of the best tuners for the 6.7 Powerstroke. It’s not CARB-exempt but at the same time, it won’t accept any emission-/delete-related tunes, either. And don’t worry about how small it is – that definitely doesn’t affect its performance.

Built-in screen offers real-time monitoring

Its 2.8-inch screen doubles up as a real-time display when you aren’t using it to navigate through various options on the device. It can monitor various parameters like exhaust gas temperature, air-fuel ratio, coolant temperature, etc. And like any other tuner worthy of this list, it can also detect and clear engine diagnostic codes.

While it doesn’t support switching on the fly, it can store 10 custom tunes and also accepts changes to vehicle parameters made to accommodate modifications. For instance, both axle ratio and tire size can be changed, the TPMS can be recalibrated/switched off, and even a speed limit can be imposed using this OBD-II programmer. It can be updated over Wi-Fi and also saves the stock tune, should you decide to revert to that in future.

What do we think of it?

Despite a smaller form factor, the SCT X4 has a lot to offer. Buyers must pay close attention to compatibility and warranty though. Overall the SCT X4 is a firm favorite and is generally considered one of the best tuners.



  • Small size
  • Good features


  • No shift-on-the-fly
  • No CARB exemption

2. Edge Products Diesel Evolution CTS2 – 85400

No products found.

The Edge Products 6.7 Powerstroke tuner offers both the ability to monitor in real-time what your Ford 6.7L Powerstroke is doing and also introduces a variety of new tunes to your truck. The 5-inch high-resolution touchscreen allows in-cabin monitoring and tuning whereas the OBD-II-connected tuner can add up to 180 hp, depending on the truck.

Not CARB-exempt

First, the basics: for Ford trucks, the Edge tuner isn’t CARB-exempt. Its use on emission controlled vehicles (road-legal) isn’t allowed as well, which means if you’re getting the Diesel Evolution, it’s gotta be for off-road/closed-circuit activities.

You can update it through the Internet, and it also offers the ability to tune shift points, adjust and correct speedometer, etc. The display comes with multiple-gauge screen layouts, with fully customizable backgrounds, and input for the rear camera.

The Diesel Evolution CTS2 is compatible with various 6.7 Powerstroke Ford trucks including the F-250 (model years 2011-2015), F-350 (2011-2015), F-450 (2011-2015), and F-550 (2011-2015). A recent update last year included the 2017-2019 models of trucks with 6.7L Powerstroke diesel. With this, there are three stages (Economy, Tow, and Extreme), with maximum power and torque increment offered at 120 hp and 220 lb-ft respectively.

What do we think of it?

Edge Products is one of the best 6.7 Powerstroke tuners, because of the experience and power boost it offers. There are mixed reviews for the product, with some being positive while others have reported that it’s not problem-free — it tends to freeze with certain vehicles, among other things.



  • Real-time monitoring
  • Good increase in power


  • Not CARB-exempt
  • Not problem-free

3. SCT Livewire TS+

SCT Performance – 5015P – Livewire TS+ Performance Tuner and Monitor – Ford Preloaded and Custom Tuning


  • Wide model fit – Fitting a wide array of Ford Models. Enter your vehicle above to verify compatibility. Please contact SCT support for assistance.
  • VEHICLE DATA OVERLOAD – The LiveWire makes it easy to read the real time vehicle data, view popular sensor data such as EGT, Air / Fuel Ratio or any other 0-5 Volt source!
  • CUSTOM TUNING – Arrives pre-loaded with Dyno proven performance tune files & holds up to 10 custom tuning files for maximum tune flexibility.
  • ADJUSTABLE INTERFACE -Make it yours with user adjustable warnings, alerts, and vehicle parameters. Reads & Clears DTC Codes.
  • HEADS UP DISPLAY – Monitor your performance at a glance with a dynamic 4″ LCD display mounted on a pillar, window, or dash. Rearview camera input.

Like the smaller X4 mentioned above, the SCT Livewire TS+ comes with tunes for a wide range of Ford products. With a larger color display, it has a better monitoring ability, and can even add up to 103 hp and 221 lb-ft. It’s compatible with the 6.7L Powerstroke Ford trucks, but we’d suggest you confirm with the seller before making a purchase.

Pre-loaded with tunes; Shift-on-the-fly available

It comes with 10 pre-loaded tunes. That’s in addition to its ability to offer shift-on-the-fly (on select trucks), read and clear engine codes, set user-adjustable warnings, among other things.

It’s not CARB-exempt but SCT maintains that the product won’t support changes to the emission system. It also aids mileage, which can be a great thing if your truck is a daily driver. The 4-inch color touchscreen comes with an ambient light sensor and can log and monitor the data. Like on other displays (such as the Edge above), you can customize the look, and you can also connect a reverse camera to it.

What do we think of it?

The SCT Livewire TS+ is a combination device. Those who’ve used the tuner have reported a substantial increase in performance, but on the other hand, one has to purchase tunes from SCT, so that’s going to be some more money out of your pocket.



  • Power increase
  • Wide Ford compatibility


  • Not CARB-exempt
  • Fee for additional tunes

4. Superchips F5 Ford Flashpaq – 1845

  • ۢ High-definition, 2.8" color screen ۢ Redesigned graphic interface for improved user experience ۢ Increased memory with faster processor for improved tuning & updating speed ۢ Performance tuning for Economy, Towing, Daily Driving, & Extreme Tuning ۢ Eliminate downshifting when climbing hills

  • ۢ Vehicle parameter monitoring capabilities ۢ Read & clear diagnostic trouble codes ۢ Compatible with other performance upgrades ۢ 2-year powertrain warranty
  • Features may vary based on year, make, & model. **Incomplete/Cab and chassis trucks not supported**

An easy-to-use handheld tuner, the Superchips Flashpaq is a great way to tune your truck but without attracting too much attention, even inside the cabin. It has a 2.8-inch color screen with a straightforward interface and offers the standard fare of features on tuners. It also gets a 2-year powertrain warranty and can be updated from the internet through USB.

Multiple power stages

If you’re looking for power upgrades you’ll be happy to learn that there are three tunes for 6.7 Powerstroke: Performance (120 hp increase), Heavy Town (48 hp increase), and Mileage XS Save (80 hp increase). You can also correct the tire size, adjust speed and rev limiters, read and clear DTCs, control the TPMS, and even fiddle with tuning for shift points and firmness.

Although Superchips maintains the device is 50-state legal, the coverage for 2011-2016 6.7L Powerstroke engined trucks is pending. So just make sure to cross-check your truck’s compatibility and the CARB status with the seller.

What do we think of it?

It improves drivability but without costing a ton or needing to do a million changes to your truck. The lack of CARB exemption and a large screen for monitoring might be some deterrents though. But otherwise, it’s a great choice. Users have noticed a power increase and many love the simplicity of the device.



  • Simple, no-nonsense tuner
  • Power increase


  • Not CARB-exempt

5. Bully Dog GTX for Ford Powerstroke

Bully Dog - 40460B - GTX Performance Tuner & Monitor - Custom Tunes and Wifi Enabled
  • Wide Make & Model Fit - Works on Ford, Dodge, Chrysler, Jeep, Chevrolet, GM, Cadillac, & Toyota applications. Enter your vehicle to verify compatibility. Please contact Bully Dog directly for support.
  • Cloud Delivery - Download updates and tunes from over Wi-Fi. Matches your Ford vehicle with available tunes and settings that fit.
  • Removable Monitor - Convenient Grab-and-Go magnetic mounting system lets you keep your monitor secure when not in use.
  • Code Clearing - Diagnose and clear trouble codes to ensure proper engine operation. Performance Logging - Data logging for real-time performance review with playback option using LiveLink software.
  • Monitor performance parameters at a glance with a mounted dynamic 5" LCD display. Control your vehicle's performance fully with preloaded & custom tune capability in an adjustable tune interface.

The thing with most tuners is that while they offer astounding features and unshackle your truck, they don’t look great. The device looks a bit out of place in the cabin (especially when we talk about the newer cabins) or the overall interface of the screen seems dated. But none of that is true with the Bully Dog GTX. It comes with a magnetically attaching touchscreen display (5-inch; capacitive touch), can be switched on in just 10 seconds, and does everything else a tuner of its caliber is expected to do.

Monitor and record performance data

You can get custom tunes from Bully Dog’s dealers, record vehicle performance data (at 35 fps) as you drive to review later, and also monitor a variety of engine parameters. The tuner can save up to 20 custom tunes, and you don’t even need to connect the device to a computer to add new tunes — it’s all done via Wi-Fi. 

Settings like axle ratio, TPMS, tire size, speed limiter, etc. can be corrected/adjusted, in addition to the inclusion of an airbox without running into a check engine warning/light. Speaking of engine error codes, you can detect and also clear those with this tuner. And since it’s a 35 fps recording, the playback of performance data is bound to be smooth. The same can be said about the capacitive touchscreen.

What do we think of it?

The Bully Dog GTX seems to be one of the few future-ready tuner combinations. The high-resolution monitor is also a big positive, in addition to the tuner itself. Confirm with the seller whether the device is compatible with your truck model before you make the purchase.



  • Good screen
  • All the features; seems ready for future


  • None

What is the Best Programmer for a 6.7 Powerstroke?

It would have to be the SCT X4 Performance Programmer. Based upon our testing, this is the best tuner.

Programmers and tuners for cars are just like amplifiers for speakers. Like how you’d need an amplifier to achieve optimum results from the speaker, by using a tuner you’ll enjoy the truck at its maximum potential when it comes to power and fuel economy. Having said that, just be careful with the extreme power tunes because that ends up creating an extra load on engine and drivetrain components, wearing them down faster.

Among the 6.7L Powerstroke programmers we’ve mentioned here, the SCT X4 and Superchips Flashpaq offer simplicity and a smaller form factor. But if you’re after a more serious approach for monitoring what your truck is doing, the Edge Products Diesel Evolution,  SCT Livewire TS+, and Bully Dog GTX are solid choices. The GTX offers a great screen and has a very quick start-up time. The Diesel Evolution offers a solid power upgrade (and assured compatibility with 2017-2019 models of 6.7L Powerstroke), and the Livewire comes loaded with Shift-on-the-fly (on select truck models).

Best 6.7 Powerstroke Tuner by Year (2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018 & 2019)

What's the best 2011 6.7 Powerstroke programmer?

If you’re looking for a tuner that supports Ford trucks with the fabled Powerstroke diesel engine, it’s hard to go wrong with the SCT X4. It has wide compatibility, so if you plan to switch to a newer truck in the future, you won’t have to spend extra on a tuner. It also comes with a 2.8-inch screen, so monitoring certain parameters is possible. It can also store 10 custom tunes, and you can also use features like imposing a speed limit.

What's the best 2012 6.7 Powerstroke programmer?
For the 2012 6.7 Powerstroke, if you don’t necessarily want a large screen or an in-dash display, the Superchips F5 makes for the right choice. Like the SCT X4, it comes with a 2.8-inch screen and can be connected directly to the OBD-II port. There are three tunes, which are accompanied by a varying degree of power increment. And not only that, but you can also set the tire size in the tuner, if you’ve opted for larger wheels. It also comes with the ability to read and clear engine codes.
What's the best 2013 6.7 Powerstroke tuner?
A secondary screen is a good way of monitoring real-time stats on your truck. And if it looks as good as the Edge Products Diesel Evolution, then it doesn’t look bad in your truck’s cabin, either. The 5-inch touchscreen system doesn’t too much space, and also enables in-cabin tuning. You can also include the feed to the reverse camera, with which the display doubles up as a rear parking monitor as well. As for the tuner, there are three preset stages (Economy, Tow, and Extreme) and can be selected depending on the operation.
What's the best 2014 6.7 Powerstroke tuner?
The SCT Livewire TS+ benefits from a 4-inch touchscreen display, added power and torque, pre-loaded tunes, and the ability to shift on the fly. That means you can change the tunes while on the move/when the truck is on. That is a rarity because most tuners require substantial time to change the tune. Also, you can log your truck’s data, and even connect the reverse camera to it. And since it’s a nice little display, it won’t look too out of place in the newer dashboard layouts also.
What's the best 2015 6.7 Powerstroke tuner?
The Bully Dog GTX is a solid choice for the 2015 6.7 Powerstroke equipped Ford trucks. The tuner comes with a 5-inch touchscreen display, which can also be removed when exiting the truck, ensuring that it doesn’t get stolen. You can add up to 20 custom tunes, whereas the high-res display can also be used to monitor and log the truck’s performance. The diagnostic trouble codes can be read and cleared, but what makes the tuner stand out is its ability to start up in a mere 10 seconds.
What's the best 2016 6.7 Powerstroke programmer?
If you have a 2016 6.7 Powerstroke engined truck and aren’t too keen on getting a standalone screen equipped tuner, the Superchips F5 Flashpaq makes for a good choice. It has some great features, offers various states of tune, and can add up to 120 hp. It doesn’t cost a lot, and stays inconspicuous as well. With that said, the onboard 2.8-inch screen enables ease of use, and the device can be updated by connecting to the Internet via USB. That means you won’t miss out on most new features/tunes of the larger-screen-equipped tuners.
What's the best 2017 6.7 Powerstroke programmer?
For the newer trucks, the Edge Products Diesel Evolution brings the best of both worlds: a good tuner and a large, responsive touchscreen. Depending on the truck, it can add up to 120 hp of max power, can be updated through Internet, has three power maps (Economy, Tow, and Extreme), and allows in-cabin monitoring and tuning.
What's the best 2018 6.7 Powerstroke tuner?
If you have a 2018 6.7 Powerstroke on one of the Ford Superduty trucks or the Ford F-450/F-550, the Bully Dog GTX is a superb choice. It claims to be the quickest to start up, taking just about 10 seconds. And it goes beyond that in impressing the user: it can hold up to 20 custom tunes, you can log and replay truck’s performance logs on the monitor, and is easy to use. It’s not the cheapest out there, but that shouldn’t stop you from enjoying the wide variety of features — it’s a one-time investment after all.
What's the best 2019 6.7 Powerstroke tuner?
A great alternative to the standalone monitor+tuner combinations for the 2019 6.7 Powerstroke can be the SCT X4 Performance Programmer. It’s a relatively smaller device so it won’t look odd in your latest truck’s new and well-appointed cabin. But with a promised power increase of up to 131 hp and a variety of features (real-time data, ability to store 10 custom tunes), don’t let its size fool you. You can also modify the axle ratio and tire size for more accurate speedometer readings.
