The 6.7L Powerstroke engine is a powerhouse, delivering impressive performance for heavy-duty applications. However, emissions control components such as the DPF (Diesel Particulate Filter), EGR (Exhaust Gas Recirculation), and SCR (Selective Catalytic Reduction) can restrict performance, decrease fuel efficiency, and increase maintenance costs. This is why many diesel truck owners opt for a delete kit, which removes these restrictive components to unlock the engine’s full potential.
If you are considering installing a 6.7 Powerstroke delete kit, this detailed step-by-step guide will walk you through the entire process. From preparing your truck to the final tuning adjustments, this guide will ensure a smooth installation while avoiding common mistakes.
Step 1: Gather the Necessary Tools and Components
Before starting the installation, ensure you have all the essential tools and components to complete the process efficiently.
Required Tools
Socket set and wrenches
Torque wrench
Screwdrivers
Pry bars
Jack and jack stands
Penetrating oil (for rusted bolts)
Required Components
EGR delete kit (block-off plates, coolant reroute)
DPF delete pipe or full exhaust replacement
CCV reroute kit (optional but recommended)
Tuner (to reprogram the ECU)
Step 2: Preparing the Truck for the Delete Kit Installation
Before removing any components, take these precautionary steps:
Ensure your truck is parked on a level surface and let the engine cool down completely.
Disconnect the battery to avoid electrical issues.
Lift the truck if necessary using a jack and secure it with jack stands.
Step 3: Removing the EGR System
Why Delete the EGR?
The EGR system recirculates exhaust gases back into the engine, which leads to carbon buildup, reduced airflow, and increased engine temperatures. Removing the EGR system reduces soot accumulation and improves engine efficiency.
Steps to Delete the EGR
1. Disconnect the battery and ensure the engine is completely cool.2. Remove the EGR valve and cooler assembly.3. Install the anodized block-off plate.4. Replace or reroute the coolant hose as needed.5. Loosen or remove fasteners and clamps securing the existing exhaust components.6. Install the front and rear block-off plates.7. Connect the new throttle valve pipe and any associated components.8. Torque all bolts and clamps to manufacturer specifications.9. Update the Engine Control Module (ECM) as required.10. Reconnect the battery.11. Start the engine and perform a thorough leak inspection.
Step 4: Deleting the DPF and Exhaust System
Why Remove the DPF?
The DPF traps soot and requires periodic regeneration, which can cause higher fuel consumption and excessive backpressure. Deleting the DPF allows the exhaust to flow freely, reducing turbo strain and increasing efficiency.
Steps to Delete the DPF
Locate the DPF filter under the truck, usually along the exhaust system.
Disconnect all sensors attached to the DPF (ensure you do not damage them).
Unbolt and remove the DPF filter along with the catalytic converter if applicable.
Install the delete pipe or replacement exhaust system.
Reconnect sensors to avoid error codes.
Step 5: Installing the CCV Reroute Kit (Optional but Recommended)
Why Install a CCV Reroute Kit?
The CCV (Crankcase Ventilation) system sends oil mist back into the intake, leading to carbon buildup and turbocharger contamination. A CCV reroute kit helps keep the intake and turbo clean, improving longevity.
Steps to Install the CCV Reroute Kit
Locate the factory CCV filter on top of the engine.
Remove the CCV filter cover and hoses connecting to the intake.
Install the new CCV reroute hose leading to a vented location.
Secure the connections and ensure proper airflow.
Step 6: Tuning the ECU for Maximum Performance
Why Tune the ECU?
After removing emissions components, the truck’s ECU must be reprogrammed to avoid checking engine lights, optimize fuel mapping, and improve performance.
Steps to Tune the Truck
Connect a tuner (such as EZ Lynk, SCT, or H&S) to the OBD-II port.
Upload the delete tune file provided by your tuner manufacturer.
Follow on-screen instructions to update the truck’s programming.
Perform a test run to ensure proper function and no error codes.
Step 7: Final Checks and Test Drive
Once all components are installed and tuned, conduct a final inspection:
Check for leaks around block-off plates and coolant hoses.
Verify that exhaust connections are properly tightened.
Ensure that the ECU tune is functioning without error codes.
Start the engine and monitor exhaust sound, throttle response, and boost levels. After a short test drive, inspect again to confirm everything is secure.
Conclusion
Installing a 6.7 Powerstroke delete kit is a highly effective way to enhance engine performance, fuel efficiency, and longevity. By removing restrictive emissions components, you can significantly reduce maintenance costs and unlock additional horsepower.
However, it is essential to consider legal regulations in your area before proceeding with a delete kit. If you are looking for a high-quality delete kit for your truck, check out DynoVox’s premium selection for durability and reliability.
