How Much Does It Cost to Delete a 6.7 Powerstroke? Full Guide

How much does it cost to delete a 6.7 Powerstroke? The promise of increased horsepower, improved fuel economy, and enhanced reliability makes removing a 6.7 Powerstroke engine attractive to Ford Super Duty owners. But behind these benefits lie significant costs, legal risks, and ethical tradeoffs. This guide details everything you need to know, from part prices and installation labor to potential fines and warranty voiding, so you can make an informed decision.

What Does It Mean to "Delete" a 6.7 Powerstroke?

Deleting involves removing emissions components and reprogramming the engine software:

Deleting the Diesel Particulate Filter (DPF):

The DPF is a soot trap in the exhaust system that traps particulate matter. Deleting it reduces back pressure.

Deleting Exhaust Gas Recirculation (EGR):

The EGR system recirculates exhaust gas back into the intake system to reduce combustion temperatures and emissions. Deleting it makes the intake air cleaner and reduces carbon deposits.

Deleting Diesel Exhaust Fluid (DEF):

DEF is a fluid used in Selective Catalytic Reduction (SCR) systems to reduce harmful nitrogen oxide (NOx) emissions from diesel engines. Deleting DEF simplifies the exhaust treatment system and reduces maintenance requirements.

Tuner:

Simply deleting the hardware is not enough. You must reprogram the Engine Control Module (ECM) to prevent error codes from appearing and going into "limp mode."

Why Would an Owner Delete a 6.7L Powerstroke?

Common reasons include:

Performance Improvement:

Unrestricted airflow can provide 40-150+ hp of additional power and torque.

Fuel Economy:

By eliminating the fuel-consuming DPF "regeneration" cycle, fuel economy can be improved by 2-5 miles per gallon (MPG).

Avoid Expensive Repairs:

By deleting the exhaust system, you no longer have to spend thousands of dollars to replace a clogged DPF or a malfunctioning EGR system.

Extended Engine Life:

Less exhaust restriction means cooler exhaust temperatures and cleaner combustion.

Average Cost Details for 6.7 Powerstroke Delete

Total cost is between $2,000 and $4,000, depending on parts, labor and model year (2011 to 2024). Here is a typical cost range you can expect:

Note : Costs may vary by model year. For example, deleting a 2017 6.7 Powerstroke engine will likely cost more due to emissions system updates.

What Is the Cheapest Way to Delete a 6.7 Powerstroke?

If you are cost conscious, some owners choose to DIY install with an affordable delete kit. SuncentAuto recommends a Powerstroke delete kit that costs about $1,113.97 and typically includes:

• EGR delete kit;
• 4-inch DPF delete race pipe (with muffler);
• Minimax tuner V2.

Doing it yourself can save you $500 to $1,000 in labor costs, but there is a higher risk of incorrect installation and voiding your warranty. If you are inexperienced, you can buy a delete kit and always consider hiring a professional to install it.

Is It Worth It to Delete Your 6.7L Powerstroke?

Let’s weigh the pros and cons:

Pros:

• Performance : Up to 150+ hp boost with smoother power.
• Savings : 2-5 mpg improvement in fuel efficiency + avoidance of DPF/EGR repairs = *break even in 1-3 years.
• Reliability : Cleaner internals extend engine life to 200,000-300,000 miles.

Cons:

• Legal risk : Potentially high EPA fines and possible failure of emissions testing.
• Void of warranty : Ford denies all emissions-related claims.
• Resale value : Modified vehicles may not be popular on the used car market.

Summary and Final Recommendations

Estimated total cost:

A complete teardown of a 6.7L Powerstroke typically costs $2,000-$4,000, depending on parts, labor, and tune-up.

Reality:

Teardowns can significantly improve performance and reliability, but they also carry serious legal and environmental risks.

Action recommendations:

Before undertaking a retrofit, research your state's emissions regulations and perform a professional cost-benefit analysis.
