Collapsible content

NO MORE EMISSIONS CODES

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

HOW DOES IT WORK?

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!

WHAT'S INCLUDED?

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

BENEFITS

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.

NO NEED TO SEND IN YOUR ECM!

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!

WHAT ABOUT THE EGR?

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.

FITMENT

This kit is only for the 2020-2022 3.0L LM2 Duramax with e46 ECM's ONLY

Additionally, most 2020-2021 models will have the compatible E46 ECM's. The 2022 models will be a mix of the compatible E46 ECM and not compatible E66 model.

Frequently Asked Questions

A Full Delete Kit removes all emissions components that commonly fail—DPF (Diesel Particulate Filter), EGR (Exhaust Gas Recirculation), and DEF (Diesel Exhaust Fluid) systems. Our kits include the tuner, delete pipes, and any required sensors or block-off plates—customized for your truck’s make, model, and year.
Most of our customers install the kit themselves with basic tools in a garage or driveway. Average install time: - DPF pipe: 1–2 hours - EGR delete: 2–4 hours - Tuning: 20–40 minutes We include guides and offer full lifetime support.
Our custom tuning disables all emissions-related codes, CELs (Check Engine Lights), and regen cycles. Once the tune is installed, the truck will stop trying to regen or enter limp mode.
Delete kits are for off-road and race-use only. They are not legal for highway use in the U.S. or Canada, especially in states with strict emissions laws (like California). Many customers in rural areas or provinces without emissions testing still choose to delete for reliability and performance.
Many customers opt to electronically disable the EGR without physically removing it, especially for a cleaner engine bay or quicker install. Our tuners support both full deletes and “leave-in-place” disable setups.
Yes. Most customers report a gain of 2–5 MPG depending on driving style, tune level, and truck setup. You’ll also eliminate DEF refills and regen cycles, which further saves fuel.
No cutting or welding is needed for most applications. Our pipes bolt up directly to factory locations and use existing mounts and gaskets. We make it easy to return to stock if needed.
Deleting the DPF will make the exhaust louder. You’ll hear more turbo spool, engine tone, and exhaust note, especially with a straight pipe. We offer optional mufflers for those who want a quieter ride.
We’re not just a parts store—we’re diesel truck owners too. Here’s why customers choose us: - All-in-one bundles, no guesswork - Lifetime support with install help, updates, and tuning questions - Fast shipping and transparent pricing - Trusted by thousands of truck owners across North America.
