What Is a Duramax Full Delete Kit?

A Duramax full delete kit answers "What is deleting a truck?" by bypassing factory emissions for unrestricted power. It targets the 6.6L Duramax engine across generations, eliminating DPF for better flow, EGR to cut carbon buildup, DEF to skip refills, and CCV to reduce oil contamination.

Ideal for delete kits for diesel trucks, these bundles – like our L5P, LMM, or LML full delete kit – are for off-road only, per EPA rules. EGR Performance kits use premium materials rigorously tested for durability, ensuring top-notch quality and trust.

Frequently Asked Questions

Q: Is deleting emissions systems legal?

A: Emissions deletes are legal only for off-road or competition vehicles. On-road use can incur fines, failed inspections, and void the factory warranty.

Q: Will a delete kit void my warranty?

A: Yes. Removing OEM emissions equipment and reprogramming the ECU will void emissions-related and often powertrain warranties.

Q: How much horsepower can I gain with a full delete?

A: With a proper delete kit and tune, expect gains of 50–150 HP, depending on engine platform, exhaust configuration, and tuning precision.

Q: Do I need a tuner after installing a delete kit?

A: Absolutely. A delete tune is required to prevent check-engine lights, disable emissions codes, and optimize performance and drivability.

Q: Can I reinstall factory emissions components after a delete?

A: Technically possible, but often expensive and complex. It requires original parts, factory tunes, and professional recalibration.

Q: How long does installation take?

A: For a mechanically adept installer, plan on 4–8 hours for full hardware removal, block-off installations, and final tune-up hookup.

Q: What additional upgrades pair well with a delete kit?

A: High-flow downpipe, 5” straight-pipe exhaust, intercooler upgrades, and performance air intake kits amplify benefits.
