What Is the Best Delete Kit for 6.7 Powerstroke: 2026 Guide

The 6.7L Powerstroke engine is equipped with a range of emission systems in order to meet emission requirements. However, emission systems such as DPF and EGR can limit performance, reduce fuel efficiency and lead to expensive maintenance costs. Therefore, many truck owners consider installing a delete kit. In this article, we will discuss the advantages and disadvantages of delete kits and guide you on what is the best delete kit for 6.7 Powerstroke engines in 2026.

What Is a Delete Kit for a 6.7L Powerstroke Engine?

A delete kit is a series of parts used to remove or bypass the emission control system of a diesel engine. The main components of a 6.7 Powerstroke delete kit typically include:

• DPF delete kit : Replaces the diesel particulate filter (DPF) to allow exhaust gases to flow freely.
• EGR delete kit : Removes the exhaust gas recirculation (EGR) system to prevent exhaust gases from returning to the engine.
• DEF delete kit : Removes the diesel exhaust fluid (DEF) system, eliminating the need to fill it with diesel exhaust fluid.
• Tuner : Reprograms the ECU (Engine Control Unit) to accommodate the removed components, allowing it to run without the emission system.

Pros and cons of a delete kit for 6.7 Powerstroke engine:

Pros:

• Improves fuel economy;
• Increases horsepower and torque;
• Reduces maintenance costs.

Cons:

• Not road legal in most areas;
• Increases vehicle's pollutant emissions;
• May void manufacturer warranty.

Why Remove the Emissions System on Your 6.7L Powerstroke?

While the emissions system reduces pollutant emissions, the emissions system on your 6.7L Powerstroke is susceptible to failures, including:

• DPF Clogs : The diesel particulate filter (DPF) can become clogged with soot, requiring frequent and expensive regeneration or replacement.
• Stuck or Faulty EGR Valve: The EGR system is susceptible to carbon deposits, which can cause the engine to overheat and become less efficient.
• DEF System Failure : A DEF system failure can cause the engine to limp and require expensive repairs.

Therefore, removing the emissions system allows the engine to run cooler and more efficiently, which reduces wear on components. Many owners who have installed the removal kit report that their trucks have significantly improved performance, especially in situations such as towing heavy loads or driving in extreme terrain. However, it is important to weigh these benefits against potential legal and environmental consequences.

Comparison of Different Types of 6.7 Powerstroke Delete Kits

SuncentAuto offers a full range of 6.7 Powerstroke engine delete kit solutions designed to meet the needs of different vehicle years, budgets, and performance goals.

How to Choose the Best Delete Kit for 6.7 Powerstroke

There is actually no single "best" kit; the best kit is the one that best suits your needs. Here are the key factors to consider before making a decision:

1. Match Your Vehicle Year

Not all delete kits for the 6.7 Powerstroke engine are compatible with all vehicle years. Due to differences in the emissions system layout of the 6.7 Powerstroke engine, a 2015 kit may not be compatible with a 2020 or 2021 truck. Always check specific vehicle year compatibility to avoid installation problems.

2. Choose Partial or Complete Delete

• Kits that only remove the EGR are suitable for modifications on a limited budget or for situations requiring only minor modifications.
• Removing the DPF lines can improve exhaust flow, but it does not address EGR-related overheating and carbon buildup issues.
• A complete DPF delete kit offers the most balanced solution in terms of performance, reliability, and long-term engine health.

If you are looking for overall optimization, then a complete removal kit is usually the best choice.

3. Assess Material Quality

High-quality stainless steel offers superior corrosion resistance, withstands high-temperature exhaust gases, and ensures a longer service life—especially suitable for tractor-trailers or heavy-duty trucks.

4. Choose a Reputable Brand

The quality of removal kits from different manufacturers can vary significantly. Look for reputable brands with comprehensive after-sales support, such as SuncentAuto, which offers a 45-day hassle-free return policy and online customer support.

5. Tuner Support

A tuner is essential before removing the emissions system; otherwise, the ECU will still detect the emissions system, causing the engine malfunction indicator light to illuminate. Additionally, the vehicle may enter limp mode, and performance may be affected.

Can You Delete a 6.7 Powerstroke without a Tuner?

No.  Tuning is required after deleting. The ECU (Engine Control Unit) is responsible for monitoring and controlling the emissions system. When you remove emissions components like the DPF and EGR, the ECU detects it as a fault. Problems include:

• The check engine light stays on;
• Limp mode activated;
• Emissions test failed;

Therefore, an ECU tuner adjusts the software to bypass emissions-related errors, ensuring a smooth running engine.

Recommended Tuners:

Mini Maxx Tuner V2

Mini Maxx Tuner V1

The Mini Maxx tuner is highly recommended for the 6.7 Powerstroke delete kit. It allows you to recalibrate the ECU, optimizing both performance and fuel economy.

Is It Legal to Install a Delete Kit on a 6.7 Powerstroke Engine?

Under US federal regulations, road vehicles must be equipped with an emission control system. Installing a delete kit for road use is illegal and may result in a fine. However, in some areas, these kits are legal for off-road or racing use.

SuncentAuto products are for legal use only. Always check local laws before modifying your vehicle.
