Hey there dieselheads, are you ready to unlock some serious horsepower from your L5P Duramax? An EGR delete is one of the best mods you can do to boost performance and improve reliability. That exhaust gas recirculation system may help your truck meet emissions, but it robs power and causes buildup in your intake and cylinders. By deleting the EGR, you’ll free up your engine to breathe deeper and run cooler. Get ready for lower EGTs, less soot, and way more power to the ground. If you have a 2017 or newer Duramax and want to unleash its full potential, here’s how to do an EGR delete in your own garage in just a few hours. The results will transform how your truck runs and make you wonder why you didn’t do this sooner. Let’s get started!

What Is an EGR Delete and Why Consider It for Your L5P Duramax

If you own an L5P Duramax, an egr delete is one of the best modifications you can make. EGR stands for Exhaust Gas Recirculation, and deleting it will give you more horsepower, better fuel economy, and a cooler running engine.

The EGR system routes some of your exhaust back into the engine to be re-burned. The problem is, exhaust gas contains particulate matter that gunks up your intake and valves over time. By deleting the EGR, all that soot and sludge won’t build up in the first place.

An EGR delete involves removing components like the EGR valve, EGR cooler, and associated hoses and pipes. Once deleted, you’ll immediately notice your L5P running better. Without exhaust gas diluting the air-fuel mixture, your engine can take bigger gulps of fresh air and make more power.

You should see gains of 50-100 horsepower or more, depending on other mods. Your engine will also run cooler without the EGR pumping hot exhaust gas back into the cylinders. Better still, your increased fuel economy can offset the cost of the delete kit in under a year.

If you want maximum power and longevity from your L5P Duramax, an EGR delete is a must. Although it’s not legal for on-road use in some areas, many owners find the trade-off for performance and engine health well worth it. Are you ready to unleash your L5P’s full potential? An EGR delete is the place to start.

The Pros and Cons of an EGR Delete on Your L5P

Deleting your Exhaust Gas Recirculation (EGR) system has some serious pros and cons to consider for your L5P Duramax.

On the plus side, an EGR delete will reduce engine heat and increase airflow, giving you more power and improved performance. Many owners report 10-20% gains in horsepower and torque. An EGR delete also reduces carbon buildup in your engine and intake over time.

However, there are downsides to consider. Removing your EGR will trigger an engine fault code and check engine light. You’ll need a tune to disable the warning, which voids your factory warranty. EGR deletes may also be illegal for on-road use in some areas due to emissions regulations.

If more power and reliability are your goals though, an EGR delete paired with a performance tune can really wake up your lp5 delete. You’ll get a louder, throatier exhaust tone too from increased airflow. Many owners say the pros far outweigh the cons if you plan to own your truck long-term.

Before deleting your EGR, check your local laws and think about how long you plan to keep your Duramax. If you want maximum power and can live without the factory warranty, an EGR delete and tune can really unleash the full potential of your engine. But if resale value or emissions compliance matter most, you may want to keep your EGR system intact. The choice is yours!

A Step-by-Step Guide to Deleting the EGR System on Your L5P Duramax

To delete the EGR system on your L5P Duramax, here are the basic steps:

Remove Intake Manifold

The first thing you’ll want to do is remove the intake manifold to access the EGR valve and tube. Loosen the clamp that secures the intake tube to the turbo inlet and disconnect the wiring harness from the manifold pressure sensor. Remove the bolts that secure the intake manifold to the cylinder heads. Lift off the intake manifold to remove it.

Remove EGR Valve and Tube

With the intake manifold out of the way, you’ll have clear access to the EGR valve and tube. Loosen the clamp securing the EGR tube to the exhaust manifold. Remove the two bolts holding the EGR valve to the intake manifold pad. Lift out the EGR valve and tube assembly.

Install Block-off Plate

Now you need to install a block-off plate in place of the EGR valve. The block-off plate seals off the EGR port in the intake manifold. Install the gasket on the plate, then install the plate using the bolts you removed from the EGR valve. Tighten the bolts to the recommended torque spec.

Reinstall Remaining Parts

Reinstall the intake manifold using a new gasket and tighten the bolts to the proper torque. Reconnect the wiring harness to the manifold pressure sensor and tighten the clamp on the intake tube. Start the engine and check for any leaks. You may need to clear any diagnostic trouble codes from the ECM to avoid the check engine light coming on due to the deleted EGR system.

With the EGR system deleted, your L5P Duramax will produce more power and efficiency. Make sure to check your local emissions laws regarding EGR deletes before performing this modification.

Conclusion

So there you have it, a complete step-by-step guide to deleting your L5P Duramax EGR system and unleashing more power. You’ve now joined the ranks of thousands of other diesel owners who have discovered the performance benefits of this mod. No more sluggish acceleration, reduced engine braking, or excess soot buildup. Your L5P can now breathe freely and make the power it was truly meant to.

You may get a check engine light, but don’t worry – it’s just the ECU looking for parts that are no longer there. An EGR delete tune will take care of that and ensure your L5P is running at optimal performance. Now get out there and have some fun with that newfound power! Your diesel will thank you for it.
