What Should I Look For When Buying a Tuner for a 6.7 Powerstroke?

Different tuners offer different results. Many inexperienced tuners attempt to create and sell a tune that ends up being sub-par. Indeed, even the best differentiate from one another: Power, mileage, ease of installation and use, as well as warranty friendliness need to be taken into consideration. 

Multiple Tune Levels

Certain tuners offer a variety of options. They could offer a racing option, a towing option, and an off-roading option, for example. Of course, most will have a substantial increase in horsepower and torque. Other tuners come without a premade tune, so you will have to find a trustworthy brand name and purchase a custom tune. 

Monitoring Parameters or PIDs

With powerful trucks, monitoring specific parameters becomes crucial, and tuners with a monitoring option gain a noticeable edge. But no matter how excellent of a tuner you purchase, a voided warranty only raises problems. Tuners that are vehicle warranty friendly, with no reflash required and no traces left in the ECU, become an important determining factor. 

Companies are improving their products by the day, and the margin of difference among the best is so small that it comes down to personal preference. But these factors should be the baseline of buying a tuner for the 6.7 Powerstroke.

The tuner has everything you need without the unnecessary details, and you can read through info in real-time through the gauges thanks to the data logging feature!

Why it Stands Out to Us

The tuner that allows you to boost your vehicle's performance, increasing horsepower and torque, unleashing the full potential of your 6.7 Powerstroke. The SCT X4 doesn't have any unnecessary features, only the proven tune files. It's a device with a simple plug and plays installation with an OBD-II port. The SCT X4 also comes with many adjustable parameters and comfortable data monitoring.

The tuner delivers a moderate increase in power, with more focus on the longevity of the vehicle. Banks Derringer is perfect if you wish to keep your truck in warranty.

Why it Stands Out to Us

Six power levels with shift-on-the-fly capability offer a setting for every condition. The tuner delivers a boost throughout the rpm range, from idle to redline.

Towing, driving comfortably, or racing; everything is possible with the Banks Derringer. 

The IDash gauge hardware provides the driver with monitoring information of EGT, boost, and a few more additional parameters. TransCommand Active Transmission Safety System modulates power during shifting, prolonging the life of your transmission while at the same time boosting shift performance, as well as smoothness.

Types of Tuners for The 6.7 Powerstroke

"Canned" Tuners

Canned tuners are developed explicitly for a certain type of vehicle that is most commonly stock, or a vehicle with very few minor modifications. They provide an overall benefit, an increase in performance and power, but they will typically not account for additional performance modifications. 

Programmers test a stock vehicle on a dyno, tweaking, and changing the tune to perfection. The canned tune must be compatible with every truck of that type, and it must be able to operate in most conditions. These tunes are cost-effective since they are mass-produced; however, they are limited to the exact model they are made for.

The Banks Derringer falls into this category.

"Canned" Tuners with Custom Tune Abilities

Canned tuners with custom tune possibilities include a tune from the manufacturer with the option of loading and flashing custom tunes made from an outside party. Custom tunes offer more potential for performance improvements since they are created for your specific truck.

After enhancing your vehicle with modifications, you have the option to purchase a custom tune that will be compatible with the modifications you have made. These types of tuners are an excellent option if you plan on modifying your truck at any point or if you want a cleaner tune.

The SCT X4 and Bully Dog BDX are in this category.

Custom Tuning Modules

Custom tuning modules are created to work with any part or modification, in turn, offering the most potential for an increase in power and performance. Custom tuning modules are purchased without a tune, which means that you will have to look for a tuning shop to create your specific tune.

They are very effective and heavily performance-oriented. The choice of which custom tune to purchase can become tricky unless you conduct proper research, and you have basic knowledge of tuning. Custom tuning modules are a perfect option if you wish to get the most out of your vehicle and only flash custom tunes.

The EZLynk Tuner reviewed here is one of these types. It also includes lifetime tune support from GDP, a respected tuner in the space. It's your one-stop-shop.

Cautions Considerations to Keep in Mind

One of the main discussing topics among the tuning community is the warranty problem. When it comes to vehicles in general, issues and problems can arise often, and certain parts can malfunction. That's why spending a bit extra on a warranty-friendly tuner will save you headaches in the long run.

A voided warranty should be expected in most cases, especially if you wish to get the most out of your vehicle. To avoid such problems, many decide to tune soon before or after the warranty expires. Of course, there are shops open to working on a tuned vehicle without the necessity of restoring the ECU to stock.

Regular high-pressure driving can cause damage to certain parts of the vehicle, and those parts can malfunction. A tune opens up the possibility for the driver to push the truck to its limits, without any restrictions. Unless the driver himself acts cautiously, takes good care of the vehicle, and restrains himself, possible problems can and will occur.

The 6.7 Powerstroke is indeed a solid, durable platform, and in order to keep it that way, treat it with care.

Common Tuner Issues

Low/Intermittent Battery Power

It's very important to keep the power supply regular during programming, otherwise old codes might not get adequately erased, and constant conflict between the old and the new codes can become troublesome. A low power supply can cause tuners to work improperly, sometimes not turning on at all. With a healthy battery, however, such issues shouldn't happen.

Poor Connections

The most common reason for a tuner to stop working correctly is a bad connection. Be careful during installation and plug in all the parts and connectors together. If the tuner works appropriately initially, but issues arise after some time, unplug the cables, disconnect everything, and put it back together. It should work as intended from there. 

Out-of-Date Software

Before flashing your vehicle, it's best to check for software updates first, especially if it's the first time you're tuning with the device. The device will need to download the drivers before it can function correctly. Loading and flashing new tunes prior to updating the software isn't advisable.

Tuner is VIN-Locked to another Truck

After connecting a tuner with a truck, it will not work with other trucks unless it has been completely removed or 'un-married' from the first one. Some tuners even have a feature called vin locking, which means that it will permanently be locked to it once a tuner is installed onto a vehicle.


These are the best of the best when it comes to the 6.7 Powerstroke. With these tuners, you'll unlock the full potential of your vehicle, increasing performance with no downsides. Choose the tuner that sounds the most appealing to you and enjoy driving your 6.7 Powerstroke like never before!
