Introduction – Thinking of Deleting Your 6.7 Powerstroke?
What is DPF/EGR Delete?
DPF (Diesel Particulate Filter) and EGR (Exhaust Gas Recirculation) systems are both designed to reduce harmful emissions from your diesel engine. While they help make your 6.7 Powerstroke more environmentally friendly, they can also negatively impact your engine's performance over time.
DPF (Diesel Particulate Filter): The DPF traps soot and other particulate matter produced during the combustion process, reducing harmful emissions. However, this filtration process can create significant backpressure in the exhaust system, which limits engine power and fuel efficiency. Over time, the filter needs to regenerate (burn off the trapped particles), which can cause issues such as decreased performance or forced regeneration cycles, especially if you frequently tow or drive in city conditions.
EGR (Exhaust Gas Recirculation): The EGR system recirculates some of the exhaust gases back into the intake air to reduce nitrogen oxide (NOx) emissions. While it helps to control air pollution, it comes at the cost of engine performance. Recirculating exhaust gases can introduce carbon buildup, reducing the engine’s efficiency and leading to potential maintenance problems.
By deleting these systems, you're removing the restrictions they impose on your engine, which often leads to noticeable improvements in power, fuel economy, and throttle response. However, you must also consider the potential legal implications and maintenance requirements.

What is DPF/EGR/DEF Delete? Is It Right for Your 6.7 Powerstroke?
The Technical Background and Function of DPF and EGR Systems
To understand whether deleting your 6.7 Powerstroke’s DPF and EGR systems is the right move, it’s crucial to first understand what these systems are and why they exist.
DPF (Diesel Particulate Filter): The DPF’s primary job is to trap soot and other particulate matter from the exhaust gases. These particles are produced when diesel fuel burns in the engine. Without a DPF, these particles would be released directly into the atmosphere, contributing to air pollution. While the DPF helps in cleaning up emissions, it comes with significant drawbacks. Over time, the filter gets clogged, leading to increased exhaust backpressure, which negatively impacts engine performance and fuel efficiency. Additionally, DPFs require a regeneration process to burn off the accumulated soot, which can be problematic during long periods of idling or city driving.
EGR (Exhaust Gas Recirculation): The EGR system recirculates a portion of the exhaust gases back into the engine’s intake. This helps lower the temperature of the combustion process and reduces NOx (nitrogen oxide) emissions, which are harmful to the environment. However, the EGR system introduces a downside: the exhaust gases contain carbon, which over time leads to carbon buildup in the intake manifold, on the valves, and other engine components. This buildup can reduce engine efficiency, throttle response, and lead to expensive maintenance down the road.
While both systems serve a crucial purpose in reducing harmful emissions, they also reduce the engine’s performance. This is where delete kits come in—by removing or bypassing these systems, you can restore the engine’s power, efficiency, and overall reliability.
Impact of Deleting DPF and EGR Systems on Your Engine
When you delete the DPF and EGR from your 6.7 Powerstroke, you’re essentially eliminating the restrictions they place on your engine. Here’s what you can expect:
Improved Engine Performance: Without the DPF, exhaust gases flow more freely, resulting in reduced backpressure and increased horsepower. Removing the EGR allows for better airflow into the engine, boosting throttle response and acceleration. The overall result is a noticeable improvement in power, especially when towing or hauling heavy loads.
Better Fuel Economy: With the increased efficiency of the engine, you’ll likely see an improvement in fuel economy. Since the engine is no longer working against the added backpressure from the DPF, it can perform at a higher level without burning extra fuel.
Enhanced Reliability and Reduced Maintenance: The EGR and DPF systems are prone to malfunction and require costly repairs or replacements. By deleting them, you remove potential sources of future problems. You’ll also avoid the ongoing costs of DPF regeneration and EGR cleaning, both of which can be expensive.
However, it’s not all positive. You’ll need to weigh these benefits against the legal implications and potential warranty issues. In some areas, deleting emission systems is illegal, and it can void your vehicle’s warranty. Always check your local laws and consider the long-term consequences before proceeding.

Legal Risks and Emissions Compliance
While the performance benefits of a DPF and EGR delete are clear, there are significant legal risks that you must consider before going through with this modification:
Emissions Laws: In the U.S., emissions regulations are governed by the EPA (Environmental Protection Agency), and removing emissions control systems such as the DPF and EGR is illegal under federal law for on-road vehicles. This could result in fines or legal action if your truck is inspected.
State-Specific Restrictions: Some states, such as California, have stricter emissions laws, and deleting the DPF or EGR could render it impossible to register your truck in that state. In these states, trucks are required to pass an emissions inspection, and a DPF or EGR delete will often result in a failure.
Selling or Trading Your Truck: A deleted truck may be harder to sell, as potential buyers may be wary of the legal risks or the potential for engine problems. Additionally, you may encounter issues when attempting to trade in your truck at a dealership.
If you're in a region with strict emissions laws, it's important to weigh the legal risks against the performance benefits. In many cases, if you don't drive in an area with stringent inspections, the benefits may outweigh the risks. However, if you live in a region with strict emission rules, it's better to consult with an expert or consider other performance options.
Warranty Implications – Impact on Vehicle Warranty and Insurance
Another important consideration is how a DPF/EGR delete will affect your truck's warranty and insurance:
Vehicle Warranty: Deleting the DPF and EGR systems could void your truck’s manufacturer warranty, especially if your truck is still under warranty. If any issues arise with the engine or emissions system, the manufacturer may refuse to cover repairs under warranty. This is something to consider if your truck is relatively new or if you plan to keep it for a long period.
Insurance: In some cases, deleting emissions systems may affect your insurance coverage. Certain insurance companies may view a modified truck as a higher risk, which could potentially lead to higher premiums. It's a good idea to check with your insurance provider before making any modifications.
While these are important risks, many owners who choose to delete these systems find that the long-term benefits (such as fewer repairs and better overall performance) make the trade-off worthwhile. However, it's crucial to be aware of the potential drawbacks before proceeding.
Resale Value and Trade-In Considerations
As mentioned earlier, one of the downsides of deleting your truck’s emissions systems is the potential impact on resale value. When you delete the DPF and EGR, you may reduce the truck’s appeal to potential buyers due to the concerns about legal compliance and the modification itself.
Limited Market: Many buyers prefer trucks in stock form, as they don’t want to deal with the hassle of legal issues or potential engine problems. While some buyers may be more interested in the performance improvements, the general market for deleted trucks is limited.
Lower Trade-In Value: If you plan to trade your truck in at a dealership, they may offer you a lower value since the vehicle has been modified. Many dealerships prefer stock vehicles to avoid complications with emissions regulations.
However, if you have the right buyer or are willing to go through a private sale, you may still be able to get a reasonable price for your deleted truck.
