Lars: Diesel Delete Expert and Enthusiast
If you own a Ford 6.7L Powerstroke diesel truck, you know it's a beast. But if you want to unlock its real power, you might be thinking about an emissions delete. This means getting rid of parts like the DPF, EGR, and DEF systems. To do this right, you need the best tuner.
A delete tuner is the brain of the operation. It tells your truck’s computer (ECU) how to run after the factory parts are removed. Choosing the right one is key to getting huge horsepower (HP) gains, better fuel economy (MPG), and a truck that runs cleaner and stronger.
In this article, I'll guide you on what to look for when choosing the best tuner for your 6.7 Powerstroke delete and recommend the top tuners available today.
What Is a 6.7 Powerstroke Delete?
Before diving into tuners, let's clarify what a 6.7 Powerstroke delete entails. The Ford Powerstroke engine has several emission-control systems that reduce harmful pollutants, like EGR and DPF. These components are meant to meet emission standards, but many truck owners choose to remove them — or delete them — for improved engine performance.
Components Involved in the 6.7 Powerstroke Delete:
- EGR (Exhaust Gas Recirculation): Recirculates exhaust gases back into the engine to lower emissions but can reduce power and fuel efficiency. Removing it requires understanding how to safely install the delete kit to prevent coolant leaks.
- DPF (Diesel Particulate Filter): Traps soot particles in the exhaust system to reduce pollutants but creates exhaust backpressure, which can hurt engine performance.
- DEF (Diesel Exhaust Fluid): Used in some models to reduce NOx emissions but adds complexity and maintenance cost.
Deleting these systems allows the engine to breathe more freely, increasing power, reducing backpressure, and potentially improving fuel economy. However, once you delete the emission systems, the ECU (Engine Control Unit) needs to be recalibrated to accommodate the changes. This is where tuning comes in.
Why You Need a Tuner After a 6.7 Powerstroke Delete
When you perform a delete on your truck, it disrupts how the ECU communicates with your engine’s components. Without the proper tuning, you might encounter several issues:
- Check Engine Light (CEL): The truck’s ECU will still expect to communicate with the deleted systems (EGR, DPF, DEF), triggering a check engine light.
- Limp Mode: The ECU may reduce engine performance to prevent damage because it senses missing or malfunctioning components.
- Reduced Performance: Without recalibrating the ECU, your truck may not achieve the optimal performance levels it could from the delete. See our guide on troubleshooting common delete problems to understand what can go wrong without a good tune.
In short: deleting the emissions systems without a tuner could leave your truck with poor performance, engine error codes, and potentially damage the engine over time.
What Does a "Delete" Tuner Really Do?
When you do an emissions "delete" on your truck, you are removing several heavy, restrictive parts. The tuner’s job is to stop your truck from showing error codes (Check Engine Light) because those parts are now gone.
The benefits of using a delete tuner are clear:
| Benefit | How It Helps Your Truck |
|---|---|
| More Power | Adds 50 to 150+ extra horsepower and torque. |
| Better MPG | Your engine runs cleaner and doesn't waste fuel trying to clean the DPF. Many owners report tangible fuel efficiency improvements. |
| Engine Life | Stops soot and carbon from going back into the engine, making it last longer. |
| No More Issues | You remove the chance of expensive DPF/EGR parts failing. |

Important: What Year is Your Ford Truck?
When looking for the best tuner, you must know your truck's model year. Ford changed the engine and computer often!
2011–2019 Powerstroke
These are the easiest years for deleting. The Mini Maxx V2, EZ Lynk, and SCT X4 all work great with models from these years. This is where you will find the most options and the best performance gains.
2020 and Newer Powerstroke
These trucks are much harder to tune. Ford has made the computer systems very secure. You need special tools and often an ECM (Engine Control Module) unlock. Options like the Commander Tuner or specific EZ Lynk setups are available, but they are generally more expensive and harder to install. Make sure to check that the tuner you buy specifically supports your exact 2020, 2021, or 2022+ model year.
How to Choose the Best Tuner for Your 6.7 Powerstroke Delete
When selecting a tuner for your 6.7 Powerstroke after a delete, here are a few key factors to consider:
- Model Year Compatibility: Ford constantly updates its engine and computer systems. It is **critical** that the tuner you choose specifically matches your truck's exact model year (e.g., 2011, 2017, 2020). This ensures the tunes work correctly and safely.
- Custom vs. Pre-Loaded Tunes: Some tuners come with basic tunes already installed (pre-loaded). However, for the best performance and a truly optimized engine, many owners prefer **custom tunes**. If you want a personalized setup, you must choose a tuner that can easily accept and run custom files from a tuning expert.
- Shift-on-the-Fly Tuning (SOTF): This is a very useful feature that allows you to change power levels while you are driving (for example, switching from a "Tow" tune to a "High Performance" tune). If you need this flexibility, choose a tuner (like the EZ Lynk) that supports SOTF capabilities.
- Display Size and Type: Do you want a small screen (like the Mini Maxx V2) to monitor engine data, or are you happy using your phone (like the EZ Lynk)?
- Customer Service: Tuning can be tricky. Make sure the seller or tuner company offers good tech support if you run into problems during the install.
Conclusion
For most 6.7 Powerstroke owners looking to delete (especially 2011–2019 trucks), the EZ Lynk is hard to beat for its modern tech and ability to get custom tunes from the best experts.
However, if you want a classic, reliable, and simple solution, the H&S Mini Maxx is still a champion. No matter which one you pick, getting a delete tuner is the best way to get serious power and reliability out of your Ford truck.
Frequently Asked Questions
