Power Gains from Egr Delete: 60 Hp and 120 Lb-ft Torque on 6.7l Cummins

by

The 6.7L Cummins engine has gained a reputation for its durability and performance. One popular modification among enthusiasts is the EGR (Exhaust Gas Recirculation) delete. This modification can lead to significant power gains, including an increase of 60 horsepower and 120 lb-ft of torque. In this article, we will explore the benefits and considerations of performing an EGR delete on a 6.7L Cummins.

Understanding EGR and Its Function

The EGR system is designed to reduce nitrogen oxide (NOx) emissions by recirculating a portion of the exhaust back into the engine’s intake. While this system helps in meeting emissions regulations, it can also introduce exhaust gases that reduce engine efficiency. By performing an EGR delete, you can remove this system entirely, leading to cleaner intake air and improved combustion.

Benefits of EGR Delete

  • Increased Horsepower: An EGR delete can provide up to 60 additional horsepower, enhancing your vehicle’s performance.
  • Improved Torque: Expect a boost of around 120 lb-ft of torque, making acceleration and towing more efficient.
  • Better Fuel Efficiency: With a cleaner intake, the engine can run more efficiently, potentially improving fuel economy.
  • Reduced Engine Deposits: Removing the EGR system can decrease the buildup of carbon deposits in the intake manifold.
  • Enhanced Throttle Response: A more direct airflow can lead to quicker throttle response and overall improved drivability.

Considerations Before Performing EGR Delete

While the benefits of an EGR delete are appealing, there are several considerations to keep in mind:

  • Legal Implications: In some regions, removing the EGR system may be illegal due to emissions regulations. Always check local laws before proceeding.
  • Warranty Concerns: Performing an EGR delete may void your vehicle’s warranty. Consult with your dealer if this is a concern.
  • Potential for Increased Emissions: Removing the EGR system can lead to higher emissions, which may not be acceptable in certain areas.
  • Engine Tuning Required: An EGR delete typically requires reprogramming the engine’s ECU to handle the changes in airflow and emissions.
  • Risk of Overheating: Without the EGR system, the engine may run hotter, necessitating additional cooling measures.

Steps to Perform an EGR Delete

If you decide to proceed with an EGR delete, here are the general steps to follow:

  • Gather Necessary Tools: You will need basic hand tools, an EGR delete kit, and possibly a tuner.
  • Disconnect the Battery: Always disconnect the battery before starting any work on your vehicle.
  • Remove the EGR Valve: Locate the EGR valve and carefully remove it from the engine.
  • Install EGR Delete Kit: Follow the instructions provided with your EGR delete kit to install it properly.
  • Reprogram the ECU: Use a tuner to adjust the engine’s ECU settings to accommodate the EGR delete.
  • Reconnect the Battery: Once everything is installed, reconnect the battery and start the engine to check for any issues.

Conclusion

Performing an EGR delete on a 6.7L Cummins can lead to significant power gains, including 60 horsepower and 120 lb-ft of torque. However, it is essential to weigh the benefits against the potential legal and mechanical implications. If done correctly and legally, this modification can enhance your vehicle’s performance and efficiency, making it a popular choice among diesel enthusiasts.
