Frequently Asked Questions

Q: What are the real benefits of deleting the EGR on a 2.8L Duramax?
A: Owners commonly report a noticeable reduction in soot buildup in the intake tract with intake runners and MAP sensors staying significantly cleaner over time. Under sustained load or towing, exhaust gas temperatures are often reduced by approximately 100–250°F compared to stock EGR operation. Improved airflow from eliminating EGR dilution supports more stable fuelling and timing when tuned and many users experience fewer maintenance issues related to sticking EGR valves, clogged coolers or recurring EGR-related fault codes. Overall reliability is improved on high-mileage, off-road or work trucks where the EGR system is a known failure point.

Q: Do I need a tuner when I install an LWN EGR delete?
A: Yes. Deleting the EGR will trigger codes and fault lights unless the ECU is retuned or an EM-OFF/disable tune is applied that removes or suppresses emissions system monitoring. 

Q: Will deleting the LWN EGR give me horsepower increases?
A: EGR delete alone is not a big power changer by itself. Most gains come from improved airflow and combining the delete with a performance tune. Some users report improvements in throttle response.

Q: Can I install this kit myself?
A: Yes. The delete kit hardware is designed for DIY installation with common tools. Most installs for similar delete kits take a few hours though proper tuning afterward is essential.
