How EGR Works in Your Vehicle & Why It’s Included Did you know that nearly 80% of the air we breathe is nitrogen? But when nitrogen gets hit with those extreme combustion chamber temperatures—over 1370 degrees—it turns into harmful nitrogen oxides. These gases exit your exhaust and enter the atmosphere. The EGR valve helps combat this by allowing some exhaust gases to recirculate back into the intake system. This dilutes the air mixture, causes it to burn slower, and reduces combustion temperatures by almost 150°C, thereby cutting down NOx production and making your exhaust cleaner. 2. Benefits of EGR Delete Kits While the EGR system is great for reducing nitrogen oxides and helping out the environment, the benefits stop there. When it comes to your engine’s performance, the EGR system can actually have negative effects. This is where an EGR delete kit comes into play. Many diesel truck owners are choosing to delete their EGR systems. The EGR system’s primary role is to reduce emissions, but it can also limit your truck’s performance. Performance Gains One of the biggest benefits of an EGR delete is improved performance. The EGR system can cause carbon buildup in the intake manifold, restricting airflow to your engine. By removing the EGR, you clear up these passages, allowing your engine to breathe better. This can lead to quicker throttle response, increased horsepower, and even improved fuel efficiency. Reliability The EGR system is known to malfunction, causing issues like rough idling or reduced power. Removing the EGR can increase your truck’s reliability. Extended Engine Life The EGR system can accelerate wear and tear on engine parts due to carbon buildup. By removing the EGR, you may extend your engine’s lifespan.

Legal Considerations of EGR Delete In the U.S., EGR deletes are illegal. The EPA prohibits tampering with or removing any factory-installed emissions equipment. Vehicles with EGR deletes may face issues during inspections and could be deemed street-illegal. 4. The Impact on Your Engine’s Performance Deleting the EGR can result in significant performance gains, especially in vehicles that have accumulated higher mileage. Superheated air from a faulty EGR can sap horsepower. Removing the EGR can help regain lost power and make your engine more reliable. 5. Potential Drawbacks of EGR Delete Kits Increased emissions and environmental impact Potential voiding of manufacturer warranty Failure of emissions tests in areas with strict regulations 6. Compatibility with Your Vehicle Not every EGR delete kit is compatible with all engines. Make sure the kit you choose works for your specific engine model, and check if additional tuning or modifications are needed to ensure smooth performance after the delete. 7. Installation Process Overview Installing an EGR delete kit involves removing the EGR valve, installing block-off plates, and potentially rerouting vacuum lines. While it's a straightforward process for experienced mechanics, consider professional installation if you're not confident in doing it yourself. 8. Cost vs. Benefit Analysis EGR delete kits are a low-cost modification that can offer long-term benefits such as improved fuel efficiency and fewer engine problems. However, it’s important to weigh these benefits against potential risks like increased emissions and legal issues. 9. Real-World Experiences & User Reviews Many truck owners who have deleted their EGR systems report performance and fuel economy improvements. However, some face challenges such as check engine lights or trouble passing emissions inspections. 10. Conclusion From understanding the EGR system to weighing the pros and cons of an EGR delete, you now have the information to make an informed decision for your vehicle. Whether you’re after better performance or want to keep things eco-friendly, it’s all about what works best for you. Thanks for reading, and until next time, keep your engines running!

Easy EGR Delete Steps for LLY, LBZ, LMM Duramax Owners

Hey guys! Welcome back to Dynovox tutorial blog. Today, we are going to talk about how to delete EGR on a LLY, LBZ, LMM Duramax. The process of LBZ is very similar for LLY Duramax and LMM Duramax. If you have an LML, that will be a different process. If you find this article useful, please leave your comment below, and if you have questions, ask in the comments or reach out to us on Dyonovox page chat box or any social platform. Anyways, let's get started!   EGR deletes, DPF deletes, and similar modifications are for off-road use only, such as race trucks. This isn't for public roads, so keep that in mind before deleting your truck. Also, you'll need to program the truck to shut off the check engine light because you can't just unplug the EGR valve without tuning the truck. I recommend programming your truck and putting on an aftermarket exhaust if you're doing an EGR delete. EGR Delete Process Let’s begin with LBZ. As mentioned, this process is very similar for LLY or LMM Duramax engines. The kit you need for LBZ will comes with a blocker plate, and other necessary components. A Dynovox 6.6L Duramax LBZ EGR Delete Kit is highly recommended here. (Don’t for get to use the code EGR10 for 10% discount and save some money.) Removing the EGR Cooler You can start by removing the EGR cooler. If you're just using blocker plates, follow along until we remove the cooler, then you'll be almost done. Once the EGR cooler is out, You can remove the downpipe and up-pipe, and install new components. First, remove the air intake pipe and disconnect the negatives on both batteries. Next, disconnect the electrical components bolted down with screws and move all the wiring loose. With the wiring out of the way, start unbolting the EGR cooler. Draining Coolant Next move, You can drain some coolant. GM removed the coolant drain on the rod, so we’ll have to pop out the fender and drain the coolant from a line there. After draining, you can get to the EGR cooler. Removing the Downpipe For the downpipe, remove the heat shield on the turbo by taking out three 10-millimeter bolts. The cover is tight, so cut it into two pieces with a zip cut for easier removal. Next, remove the downpipe’s heat shield and then the downpipe itself, sliding it out through the bottom. Exhaust and Up-Pipe Removal Remove the wheel and fender for more room. Loosen the exhaust, then remove the heat shield bolts. Unbolt the up-pipe from the exhaust manifold and the turbo. Use a ratchet to loosen the bolts. If bolts are tight, heat them up to ease removal. Carefully remove the up-pipe, ensuring no bolts snap. Final Steps Compare the old downpipe with the new one—always use aftermarket for better air flow and easier installation. Finally, replace the components, ensuring everything is securely bolted and connected.  That's it! If you followed along, your EGR delete should be complete.
