Frequently Asqued Questions

What is a Duramax delete kit, and why do diesel owners install one?
A Duramax delete kit is engineered to remove emissions-control components such as the DPF (Diesel Particulate Filter), EGR (Exhaust Gas Recirculation), and DEF systems. These kits are used by off-road enthusiasts and towing professionals looking to eliminate restrictions, reduce maintenance issues, and unlock the full performance potential of their Duramax diesel. Whether you’re driving a 2012, 2013, or 2015 Duramax, TunerDepot offers model-specific delete solutions tailored for your build.
What’s included in a typical GM Duramax delete kit?
Most kits—such as the 2011–2016 LML EGR delete or the 2013 Duramax DEF delete kit—include all required block-off plates, hardware, coolant reroute hoses, and gaskets for a complete installation. Each kit is designed for year-specific fitment, ensuring a clean, secure, and leak-free result.
When should I install a Duramax delete kit?
A delete kit is recommended when optimizing your truck for dedicated off-road use, heavy towing, or race applications. If you’re running a 2016 Duramax and dealing with DEF or EGR-related issues, a DEF delete kit can improve reliability and performance. TunerDepot offers solutions for nearly every Duramax generation, with options built for power and durability.
How does a Duramax tuner or programmer work with a delete kit?
A Duramax tuner—such as EFI Live, EZ Lynk, or similar—reprograms your truck’s ECM to account for the deleted emissions systems. Proper tuning ensures that fueling, turbo boost, and timing are recalibrated for optimal performance. Pairing your delete kit with the right programmer is essential for smooth operation and avoiding limp mode or fault codes.
Can I use a DEF delete kit with a tuner on a 2016 Duramax?
Yes. A 2016 Duramax DEF delete kit is fully compatible with most custom tuners on the market. After the DEF system is removed, the programmer disables related sensors and regens, allowing your truck to run efficiently without emissions-related errors.
