The 3.0L LM2 Duramax Full Delete Bundle for 2020–2022 Silverado 1500 and Sierra 1500 removes the DPF (Diesel Particulate Filter), DEF (Diesel Exhaust Fluid), and CAT from your truck, with the EGR system electronically disabled by the tune so you just unplug the sensors after installation.

One thing to verify before you order: this bundle is only compatible with the e46 ECM and will not work on e66 ECM models. The sticker on the back of your ECM tells you which one you have. Most 2020–2021 LM2 trucks run the e46, while 2022 models are a mix, so check first. It does not fit e66 models, 6.6L Duramax engines, the 2.8L Canyon/Colorado, or any non-LM2 platform. Call (888) 830-2588 if you're unsure.

The bundle includes the Commander Tuner with all accessories, 16 tuner credits split as 8 for tuning and 8 for the ECM unlock service, a 3" T-409 DPF & CAT delete pipe, and CAN Bus plugs that replace the NOx and DEF module connectors. The tune is a single file, so you choose one setting at setup: +20HP, +40HP, or +60HP. A Windows 10+ laptop is required for the unlock and tune install, and Mac isn't compatible.

The LM2 requires an ECM unlock before the delete tune can be applied, and the GDP Commander handles that in place, so there's no shipping your ECM anywhere. The CAN Bus plugs send a closed signal to the ECM where the removed sensors used to be, preventing codes. Professional installation is recommended for the DPF/CAT pipe, since engine bay components have to come out for access. Full tech support for the tune and unlock process is included.

For off-road/competition use only.
