Full DPF/DEF/EGR Delete Kit with EZ Lynk | GM Duramax 3.0L LM2 E46 | 2020–2022

3.0L Duramax LM2 Full Delete Kit with EZ Lynk Auto Agent 3 (2020–2022)

Upgrade your 2020–2022 Chevrolet Silverado 1500 or GMC Sierra 1500 with a complete 3.0L Duramax LM2 Delete Kit featuring EZ Lynk Auto Agent 3. This package combines custom ECM tuning, a 3-inch CAT & DPF delete exhaust, an EGR delete kit, and CAN BUS connection hardware.

Designed specifically for compatible LM2 engines equipped with the E46 ECM, this kit supports DPF, DEF/SCR, and EGR system modifications through vehicle-specific calibration and matching components.

Unlike conventional OBD2 tuning packages that require a separate ECM send-in service, the EZ Lynk solution supports the applicable E46 unlock and flashing process directly through the vehicle's diagnostic port.

No ECM removal or shipping required for the supported E46 configuration.

Designed for off-road and racing use.

What's Included in the 3.0L Duramax EZ Lynk Delete Kit

• EZ Lynk Auto Agent 3: A wireless OBD-II programming and diagnostic interface that connects to your compatible smartphone through the EZ Lynk Auto Agent app. It enables cloud-based tune delivery, ECM programming, diagnostic monitoring, and communication with your tuning provider.

• Custom LM2 E46 Delete Tune: Vehicle-specific ECM calibration supplied through the EZ Lynk platform. Available in two power configurations: Level 1 (+0 HP) and Level 2 (+20 HP).

• E46 ECM Unlock Support: The supplied EZ Lynk tuning solution supports the applicable E46 unlock and flashing process with the ECM installed in the vehicle. No separate bench unlock service or ECM shipment is required.

• 3-Inch CAT & DPF Delete Exhaust: Stainless steel exhaust components designed to replace the factory catalytic converter and diesel particulate filter sections.

• 3.0L Duramax EGR Delete Kit: Application-specific hardware for removing the original EGR valve and cooler assembly.

• CAN BUS Plug Kit: Connection components matched to the LM2 E46 application.

• Supporting Installation Hardware: Applicable hardware supplied with the exhaust and EGR components.

Vehicle Compatibility

This EZ Lynk delete kit is specifically designed for GM 3.0L Duramax LM2 diesel pickups equipped with the E46 ECM.

Important Compatibility Note: Some late-production 2022 GM 3.0L Duramax trucks use an E66 / Global B ECM instead of E46. This kit is not compatible with E66-equipped vehicles or 2023+ LZ0 Duramax applications.

Confirm your ECM identification before ordering.

Performance & Tuning Options

The included EZ Lynk custom tuning is designed for the 3.0L LM2 Duramax engine with supported emissions-system modifications.

Two fixed calibration options are available.

Available Power Levels

Both options provide custom tuning matched to the vehicle and installed hardware.

Please Note: These are individual fixed calibrations. Shift-on-the-Fly (SOTF) power switching is not available with this package. Level 1 is not the original factory stock calibration.

Expected Benefits

• Reduced exhaust restriction with the supplied 3-inch exhaust components

• Calibration matched to the modified emissions-system configuration

• No supported DPF regeneration requests after the applicable hardware modifications

• Elimination of supported DEF/SCR monitoring associated with the removed equipment

• Improved throttle response and drivability potential

• Access to supported diagnostics and monitoring through EZ Lynk

• Convenient smartphone-based tune management

Actual performance, fuel economy, and drivability depend on the selected calibration, vehicle condition, and installed components.

Why Choose the EZ Lynk Delete Kit?

No Separate ECM Send-In Service

For supported LM2 E46 applications, the EZ Lynk solution handles the required unlock and programming process directly through the vehicle's OBD-II connection.

This eliminates the need to remove and ship your ECM for a separate bench unlock.

Wireless Smartphone-Based Tuning

EZ Lynk Auto Agent 3 connects your truck with the Auto Agent application, allowing you to receive supported custom calibrations and access available diagnostic features from your smartphone.

Complete Matched Package

The kit combines ECM tuning, exhaust hardware, EGR delete components, and CAN BUS plugs intended for the LM2 E46 application.

Two Available Power Options

Choose between a stock-power (+0 HP) calibration and a mild +20 HP performance option according to your intended setup.

Cloud-Based Tune Delivery

Your custom calibration is supplied through the EZ Lynk platform rather than preloaded as a traditional handheld tuner file.

How the EZ Lynk Delete Kit Works

The EZ Lynk Auto Agent 3 connects to the vehicle's E46 ECM through the factory OBD-II diagnostic port, allowing custom tuning without a separate ECM unlock service.

The installation process follows three main steps:

1. EZ Lynk Setup: Connect the EZ Lynk Auto Agent 3 to the OBD-II port, pair it with a compatible smartphone, and access the supplied custom calibration through the Auto Agent app.

2. Tune File Installation: Flash the correct vehicle-specific tune file to the ECM using EZ Lynk. Make sure programming is completed successfully before proceeding with any mechanical modifications.

3. Hardware Installation: After successful ECM programming, install the supplied 3-inch CAT & DPF delete exhaust, EGR delete kit, and CAN BUS plug kit according to the provided instructions.

The custom tune supports the selected hardware configuration. It does not repair unrelated engine, turbocharger, transmission, electrical, or fuel-system faults.

Installation Information

The EZ Lynk interface simplifies the electronic programming process, but installation of the mechanical components still requires appropriate tools and experience.

Professional installation is recommended.
