How to Delete a 6.7 Powerstroke: Complete Step-by-Step Guide

6.7 Powerstroke

The 6.7L Powerstroke engine is known for its robust performance and reliability, but factory-installed emission systems like DPF (Diesel Particulate Filter), DEF (Diesel Exhaust Fluid), and EGR (Exhaust Gas Recirculation) can limit its true potential. By removing these systems, you can unlock better performance, improved fuel efficiency, and extended engine life.

This guide, written by Lars, a professional SPETUNER modification expert, will walk you through the process of deleting a 6.7 Powerstroke engine using the SPETUNER DPF/DEF/EGR Delete 2011-2019 6.7L Powerstroke All-in-One Kit, an off-road-only solution designed for enthusiasts looking to optimize their trucks.

Introduction

Can a 6.7 Powerstroke Be Deleted?

Yes, it can, but emission system deletion is subject to local laws and regulations. This guide is intended for off-road use only. Before starting, ensure compliance with legal requirements in your area.

Is Deleting a 6.7 Powerstroke Worth It?

For off-road users, deleting a 6.7 Powerstroke provides significant benefits:

  • Increased horsepower (up to 50-70 HP, depending on tuning).
  • Improved throttle response and reduced turbo lag.
  • Lower maintenance costs by eliminating soot buildup in emission systems.

Tools and Preparation

Essential Tools

  • Socket wrench set (common sizes: 10mm, 13mm, 15mm)
  • Penetrating fluid (e.g., WD-40)
  • Pry bars and exhaust hanger tools
  • Zipties and spare gaskets

SPETUNER All-in-One Kit Components

This comprehensive kit includes everything you need:

  • Mini Maxx V2 Delete Tuner: Enables ECU recalibration to disable emission systems and enhance engine performance.
  • EGR Delete Kit: Removes the EGR system to improve combustion efficiency and reduce carbon buildup.
  • DPF Delete Race Pipe: Optimizes exhaust flow by replacing the factory DPF, lowering backpressure and improving turbo performance.

Pre-Tuning the Truck

  1. Connect the Mini Maxx V2 Delete Tuner to your vehicle’s OBD port.
  2. Follow the on-screen instructions to disable the DPF, DEF, and EGR systems.
  3. Select a preset or custom tune for your engine.

Step 1: Removing the DPF and DEF Systems

1. Disconnect Sensors

  • Locate and unplug all sensors connected to the exhaust system, including the DEF injector.
  • Use a pry tool to carefully remove wire clips and secure the loose wires with zipties.

2. Remove Factory Exhaust Components

  1. Spray penetrating fluid on exhaust bolts and hangers to loosen connections.
  2. Start from the rear of the truck, removing the tailpipe and progressively working toward the DPF and SCR systems.
  3. Use exhaust hanger tools or a pry bar to release the exhaust system from its mounts.

3. Install the SPETUNER DPF Delete Race Pipe

  1. Begin with the 4-inch pipe from the kit and work your way to the 5-inch section.
  2. Use the provided clamps to secure each section of the pipe.
  3. Ensure all connections are tight and no gaps are present.

How Much HP Does Deleting a 6.7 Powerstroke Add?

With the factory DPF and DEF systems removed, along with proper tuning, your 6.7 Powerstroke can gain up to 50-70 HP.

Step 2: Removing the EGR System

1. Drain Coolant

  • Locate the coolant drain valve on the driver’s side of the truck.
  • Open the valve to drain the coolant completely. Remove the radiator cap for faster drainage.

2. Remove EGR Components

  1. Remove the intake pipe and air filter housing for easier access.
  2. Spray penetrating fluid on EGR cooler bolts to loosen them. Work patiently to avoid breaking bolts.
  3. Carefully remove the EGR cooler and associated piping.

3. Install the SPETUNER EGR Delete Kit

  1. Replace the EGR system with the provided block-off plates.
  2. Ensure all O-rings and gaskets are intact for a proper seal.
  3. Cap off unused sensor connectors and secure them with zipties.

Is Deleting a 6.7 Powerstroke Worth It?

Yes, for users seeking improved performance and lower maintenance. Removing the EGR system prevents carbon buildup, enhancing engine responsiveness and longevity.

Step 3: System Restoration and Testing

1. Restore the Coolant System

  • Reconnect the coolant lines and close the drain valve.
  • Refill the system with new or filtered coolant.
  • Start the engine and run it for a few minutes to purge air from the system. Recheck coolant levels and top off if necessary.

2. Check for Leaks

  • Inspect all block-off plates, pipe connections, and coolant lines for leaks.
  • Tighten any loose clamps or fittings.

3. Performance Testing

  • Take the truck for a test drive, preferably on a highway, to evaluate performance under load.
  • Monitor engine response and fuel efficiency improvements.

How Long Will a Deleted 6.7 Powerstroke Last?

With proper maintenance and regular inspections, a deleted 6.7 Powerstroke can last over 300,000 miles, thanks to reduced soot buildup and lower operating strain on the engine.
