6.7 Powerstroke engine found in Ford Super Duty trucks is a workhorse known for its power and durability. However like many modern diesel engines it comes equipped with emissions control systems like Diesel Particulate Filter (DPF). While DPF helps reduce harmful emissions many truck owners have reported issues with reduced performance and fuel economy. As a result some consider installing a 6.7 Powerstroke DPF delete kit to enhance fuel mileage performance and engine longevity.
What Is a DPF Delete?
DPF is part of truck’s emissions system designed to trap and burn soot particles fromexhaust. Over time it can become clogged requiring frequent regeneration cycles or even replacement. A DPF delete involves removing DPF system entirely and reprogramming engine control module (ECM) to run without it. This is done using a DPF delete kit for the 6.7 Powerstroke which typically includes a replacement exhaust system and a tuner or programmer.
MPG Gains After DPF Delete
One of main reasons truck owners consider deleting DPF is to improve fuel economy. After installing a 6.7 Powerstroke DPF delete kit many drivers report a noticeable increase in miles per gallon (MPG). On average gains range from 2 to 5 MPG depending on driving conditions modifications and overall vehicle health.
Before t delete stock 6.7 Powerstroke trucks usually average around 12–15 MPG in combined city and highway driving. After a DPF delete it’s not uncommon to see numbers in 16–20 MPG range especially during highway trips or under light load conditions. For those towing heavy loads difference can still be significant even a 2–3 MPG gain translates into real-world savings over long distances.
Other Benefits of DPF Deletion
While improved fuel efficiency is a major draw it’s not only benefit of using a DPF delete kit on the 6.7 Powerstroke. Removing DPF can also:
- Increase horsepower and torque: With less exhaust restriction engine breathes more freely which can lead to noticeable performance gains.
- Improve throttle response: Drivers often report a smoother more responsive driving experience.
- Extend engine life: Reducing need for frequent regeneration cycles and lowering exhaust gas temperatures can lead to less wear on engine and turbo components.
- Lower maintenance costs: Without DPF there’s no need for costly filter replacements or cleaning services.
Legal and Environmental Considerations
It’s crucial to remember that many places including the US forbid deleting DPF for on-road use. Tampering with emissions control devices on vehicles that are driven on public roads is strictly prohibited by the Environmental Protection Agency (EPA). Even owning or installing a DPF delete kit for a 6.7 Powerstroke can lead to fines and penalties for both customers and repair shops.
Nevertheless some truck owners install delete kits on vehicles that are only used for racing or off-roading where laws might not be applicable. Make sure the vehicle is never used on public roads in its modified state and that you are fully aware of the laws in your jurisdiction if you are thinking about taking this route.
Final Thoughts
For drivers who use their dpf delete kit 6.7 powerstroke trucks to transport heavy loads or travel long distances a DPF delete can result in significant fuel economy gains. With the right 6.7 Powerstroke DPF delete kit, there is the option to increase performance reduce long-term maintenance and boost MPG. But it’s important to weigh those advantages against legal and environmental consequences of lifting emissions controls. If you want to modify your truck yourself do your homework and consider working with a diesel performance expert.
