GM/Chevy Duramax 3.0L LM2 Full Delete Bundle | 2020-2022

When you install the delete tune, your truck will no longer have emission related codes or warnings. 

This includes all

1) “See Dealer” codes

2) Check engine codes

3) “Exhaust system service required” codes

4) Limp Mode codes

5) Other emissions related diagnostic codes

The Full Delete bundle(s) will permanently upgrade your truck to work without the suffocating factory emissions system.

This means you can remove ALL emissions-related parts and sensors for good, including the:

- DPF (Diesel Particulate Filter)

- DEF tank (Diesel Exhaust fluid)

- CAT (Catalytic Converters, including DOC and NOX, etc.)

This is made possible by our custom delete tunes that wipe away the emissions system from your truck’s computer.

Once the pesky emissions system is “deleted” from your truck’s programming, you can proceed to remove all of the parts that are holding your diesel back from running at its best.

This product will require your to Unlock your ECM with the GDP commander tool.

Please note, this product is only compatible with trucks between 2020-2022 3.0L models with a e46 ECM only!

The Bundle Includes:

1) Commander Tuner and all required accessories.

2) 16 credits ( 8 for tuning, 8 for unlock service via Commander tuner)

3) 3” T-409 Rust Resistant DPF & CAT Delete Pipe

4) Can Bus Plugs

By deleting the factory emission system which has been suffocating your diesel, you’ll immediately notice a night and day difference. It will perform better in every imaginable way, including speed, fuel economy (5 mpg increase on average), and fewer trips to the autobody shop.

Over time, the kit pays for itself with the fuel savings alone. That’s not even considering how many costly trips to the dealer you’ll be saving yourself.

The last benefit is peace of mind, knowing your truck no longer has a ticking time bomb attached to it.

The GDP command will unlock your ECM and allow tunes to re-program your ECM!

This means no downtime and no risk of your ECM getting lost or damaged in transit!

The EGR delete kit for these trucks that was developed has had too many fitment issues for us to feel comfortable to include in our package.

The Delete tune will full shut down the EGR system and the valve will remain closed. Simply unplug the EGR sensors after installing the delete tune and you are good to go.
