What Are The Pros And Cons Of Deleting 6.7 Powerstroke

Diesel engines have come a long way regarding power, efficiency, and emissions reduction. However, some enthusiasts still seek to maximize their engine’s performance by removing the emissions control systems. This is particularly true for the 6.7 Powerstroke, a popular diesel engine found in Ford Super Duty pickup trucks.

“Deleting” the 6.7 Powerstroke involves removing the Diesel Particulate Filter (DPF), Exhaust Gas Recirculation (EGR), and Diesel Exhaust Fluid (DEF) systems. While this modification can increase horsepower and fuel efficiency, it has potential drawbacks, including increased emissions, engine damage, and warranty issues. Let’s find out what are the pros and cons of deleting 6.7 Powerstroke and the environmental and legal implications. We’ll also find out the cost of this modification and help you decide whether it’s worth it for your needs.

Pros and Cons of Deleting 6.7 Powerstroke

Pros

Deleting a 6.7 Powerstroke can offer several benefits in terms of engine performance and maintenance. Here are some of the potential pros of deleting a 6.7 Powerstroke:

Increased Performance: One of the main reasons people choose to delete a 6.7 Powerstroke is to increase performance. The DPF, EGR, and DEF systems can restrict airflow and reduce power output. By removing these systems, the engine can generate more horsepower and torque and run more efficiently.
Fewer Maintenance Costs: If they fail, the DPF, EGR, and DEF systems can also be expensive to repair or replace. By deleting them, you eliminate the need for these costly repairs.
Better Engine Sound: The DPF and muffler can restrict the engine’s exhaust, making it sound quieter and less aggressive. Deleting these components can result in a louder, more aggressive exhaust note, which may be desirable for some enthusiasts.

Improved Fuel Efficiency: Without the DPF and EGR, the engine can run more efficiently and achieve better fuel economy.

Cons

While there are potential benefits to deleting a 6.7 Powerstroke, there are also several drawbacks. Below are some of the potential cons of deleting a 6.7 Powerstroke:

Environmental Impact: The DPF, EGR, and DEF systems are designed to reduce harmful emissions from the engine. Removing 6.7 Powerstroke increases the number of pollutants released into the environment, contributing to air pollution and harming public health.

Potential Engine Damage: The emissions control systems are designed to protect the engine from excessive wear and tear. Deleting these systems can increase engine stress, leading to premature failure or other damage.
Warranty Issues: Deleting the emissions control systems can void the manufacturer’s warranty. This means that any repairs or replacements needed due to engine damage may not be covered by the warranty, resulting in additional costs for the owner.

Environmental Impact Of Deleting A 6.7 Powerstroke

Deleting a 6.7 Powerstroke has a significant impact on the environment. The emissions control systems removed during the deletion process are designed to reduce harmful pollutants, including particulate matter and nitrogen oxide emissions. These pollutants contribute to air pollution and can adversely affect humans and the environment.

Removing the Diesel Particulate Filter (DPF) increases particulate matter emissions from the engine. Particulate matter is an air pollutant consisting of tiny particles that can be inhaled into the lungs and cause respiratory problems. Removing the Exhaust Gas Recirculation (EGR) system can increase nitrogen oxide emissions, contributing to smog and acid rain.

Furthermore, removing the Diesel Exhaust Fluid (DEF) system may lead to higher nitrogen oxide emissions, a significant contributor to smog. The DEF system uses a non-toxic urea-based solution to convert nitrogen oxide into harmless water and nitrogen, reducing the engine’s emissions.

Warranty Issues With Deleting A 6.7 Powerstroke

Deleting a 6.7 Powerstroke can also have warranty implications. Most vehicle manufacturers offer a vehicle warranty covering repairs and replacements of specific components within a certain time frame. However, modifying the engine, including deleting the emissions control systems, can void the manufacturer’s warranty.

When a vehicle is modified, it is no longer in compliance with the manufacturer’s specifications, and the warranty may not cover any issues arising from the modification. This means that any repairs or replacements needed due to engine damage may not be covered by the warranty, resulting in additional costs for the owner.

If the engine is modified and returned to the dealer for repairs or maintenance, the dealer may refuse to work on the vehicle or charge additional fees for repairs.

You must therefore consider these issues before deciding to modify the engine. It may be worth consulting with a professional mechanic or dealer to understand the potential warranty implications before making any modifications.

How Much Does It Cost To Delete a 6.7 Powerstroke

The cost of deleting a 6.7 Powerstroke can vary depending on several factors, including the make and model of the vehicle, the extent of the modifications, and the labor costs involved. Here are some of the potential costs associated with deleting a 6.7 Powerstroke:

Parts: The cost of the parts needed to delete a 6.7 Powerstroke can range from a few hundred dollars to several thousand dollars. The most common components needing replacement include the DPF, EGR, DEF systems, exhaust systems, and tuning software.
Labor: The labor cost can vary depending on the mechanic or shop performing the work and the extent of the modifications. Labor costs can range from a few hundred dollars to several thousand dollars.

Tuning Software: Tuning software is often necessary to modify the engine to run correctly without the emissions control systems. This software can cost several hundred dollars.

Verdict

Weigh the pros and cons of deleting 6.7 Powerstroke and consult a professional mechanic or dealer to understand the potential implications and costs before taking any step. It may also be worth exploring alternative ways to increase engine performance and fuel efficiency that do not involve deleting the emissions control systems. Ultimately, weighing the potential benefits and drawbacks is crucial in making an informed decision about modifying your 6.7 Powerstroke engine.
