User Tips, Install Notes & Precautions
Install Tips & Real-World Feedback
If you're mechanically inclined, installing the full delete system on a 2020 L5P or 2024 Duramax is straightforward for the most part. The DPF and CCV removal involve basic unbolting and rerouting. However, the EGR system can be tricky—bolts connecting the EGR inlet pipe to the exhaust manifold are notorious for snapping. We strongly recommend having sharp drill bits and a helicoil thread repair kit on hand before starting.
Tuning Considerations
While the OBDII tuning interface is included, tune files and credits are sold separately. For best results, choose reliable tuning partners such as AMDP or EZLynk with GDP tunes, especially for newer 2024 Duramax models. Some ECUs may still be locked and require custom solutions.
Keep OEM Parts & Protect Wiring
Many owners suggest keeping all OEM emissions parts if you ever plan to revert the truck to stock or trade it in. Also, for any unplugged connectors under the truck, apply dielectric grease and use sealed plug caps to prevent corrosion and ensure safe long-term operation.

FAQs
Q1: Can I reuse this 2020 L5P delete kit on a 2024 Duramax?
A1: The hardware components (DPF/CCV/EGR delete parts) may be compatible, but ECU tuning support differs significantly. The 2024 Duramax uses a more secure control module, and tunes developed for 2020 may not apply. Always check with your tuner before reuse.

Q2: Will installing a 2024 Duramax delete kit affect my truck’s resale value?
A2: Yes, it can. While performance enthusiasts may value the mod, dealerships typically reject deleted vehicles for trade-in. To preserve value, store all OEM emissions parts and consider a reversible tuning strategy.
Q3: Does deleting impact DEF usage and regeneration cycles?
A3: Absolutely. Once your DPF and SCR are deleted, DEF is no longer required, and regen cycles are disabled. This results in lower operating costs and eliminates DEF-related maintenance. However, this is strictly for off-road use.
Q4: Do I need custom tunes or are pre-loaded tunes enough for a full delete?
A4: Pre-loaded tunes can work, but they may not match your truck’s setup or driving goals. For optimal reliability, especially on a 2024 Duramax delete kit, request a VIN-matched custom tune from a trusted provider.
Q5: Will I hear a difference in exhaust sound after installing the delete kit?
A5: Yes. With the DPF and muffler removed, you'll hear a much deeper, more aggressive exhaust tone. Many users with 5" straight pipe setups on 2020+ L5P Duramax trucks describe it as "truck should sound like a truck."
Q6: Is the tuner included in the delete kit locked or open to additional tuning?
A6: SPELAB's tuner interface is unlocked, allowing for custom tunes to be flashed via OBDII. However, tunes and HP Tuners credits are sold separately, giving you the flexibility to work with your preferred calibration shop.
Q7: Will I see fuel economy gains after deleting my 2020 or 2024 Duramax?
A7: Many owners report increases from 13–15 MPG (stock) to 17–20 MPG post-delete, depending on driving habits and load. This is due to eliminating exhaust restriction and reducing regen fuel burns.
Q8: Can I restore my truck to factory emissions setup later?
A8: Yes—if you've retained all OEM parts and protected wiring plugs. Many users reinstall stock systems when selling or moving to emissions-restricted areas. Plug cap kits and dielectric grease are highly recommended during the delete process.
Q9: What kind of maintenance is required after installing this kit?
A9: Regular maintenance checks on the exhaust and filtration systems are recommended to ensure optimal performance and longevity.
Q10: Can I use this kit in all driving conditions?
A10: Yes, the components are designed to withstand various driving conditions, but always follow recommended maintenance and inspection schedules.
Q11: Where can I get support if I encounter issues with the kit?
A11: You can contact SPELAB customer service via email at service@spelabautoparts.com for any questions or support needed.
