Full DEF Delete Kit | GM/Chevy Canyon/Colorado Duramax LWN 2.8L | 2016

2016 Duramax 2.8 DEF Delete Kit

The 2016 GM/Chevy Canyon/Colorado 2.8 Duramax DEF delete kit is an All-in-One bundle built specifically for Chevrolet Colorado and GMC Canyon pickup trucks equipped with the 2.8L LWN diesel engine. The package combines vehicle-specific ECU tuning, a full 3-inch Turbo-Back Exhaust System, and EGR valve and cooler removal hardware for a complete off-road setup.

The system is designed to replace the restrictive factory DPF, DEF/SCR, and CAT exhaust components while removing the EGR hardware responsible for exhaust gas recirculation. Matching tuning adjusts the engine controls for the new configuration, eliminates regeneration requests for the removed particulate filter, and supports normal operation after the emissions hardware is removed.

Why Choose This Kit

• 2016-specific LWN tuning - this model year uses its own ECU configuration and should not be mixed with 2017-2021 tuning files.
• Two practical tune choices - select Stock Optimized (+0 HP) or Light Towing (+20 HP).
• Complete hardware package - includes the exhaust, EGR removal components, block-off parts, and required installation hardware.
• 3-inch Turbo-Back Exhaust - replaces the restrictive factory exhaust section for improved flow from the turbo back.
• Tuning and hardware in one bundle - avoids sourcing mismatched parts separately.

This setup is best suited to owners who want one coordinated package instead of combining an unrelated tuner, exhaust pipe, EGR parts, and calibration from different applications.

Vehicle Compatibility

The 2016 LWN DEF delete kit is specifically configured for the first model year of the North American 2.8L Duramax Canyon and Colorado. GM revised the tuning configuration for 2017+, so a later truck should use the corresponding 2017-2021 product instead. HP Tuners also lists 2016 Colorado and Canyon 2.8 Duramax applications separately from 2017+ vehicles in its supported-vehicle data.

Kit Components

• ECU Tuning Interface - connects the truck to the required tuning software so the factory stock file can be read and the custom calibration written back to the ECU. A Windows laptop is required for the tuning process.
• Custom Tune File - adjusts the ECU for the changed DPF, DEF/SCR, and EGR configuration. The current product offers Stock Optimized and Light Towing calibrations.
• 3" Turbo-Back Exhaust System - replaces the factory DPF, CAT, and SCR exhaust section with a freer-flowing system designed to maximize exhaust flow.
• EGR & Cooler Delete Kit - removes the factory EGR valve and cooler to stop exhaust gas and soot recirculation through the intake.
• Block-Off Plates and Hardware - provide the seals, plates, clamps, brackets, and fasteners required for the mechanical removal.
• Installation Instructions - step-by-step guidance is provided to help with both the tuning and mechanical portions of the upgrade.

Tuning & Performance

The 2016 2.8 Duramax DEF delete kit uses a fixed Single calibration rather than an SOTF tune. The current product selector provides two options:

Stock Optimized maintains factory-level power while modifying the ECU for the removed emissions systems. Light Towing adds 20 HP and is intended for owners who want a moderate increase in towing and everyday performance.

Before tuning, the vehicle's original stock file and required vehicle information are read through the tuning interface. The custom file is then written back to the ECU. HP Tuners licenses supported 2016 Colorado and Canyon 2.8 Duramax vehicles through its credit-based system, with the 2016 application listed separately from later model years.

Removing the restrictive factory filter and exhaust section allows freer flow and eliminates DPF regeneration for the removed hardware. Throttle response and usable torque may improve, while the Light Towing calibration provides the confirmed power increase. Fuel efficiency, boost response, and overall performance still depend on vehicle condition, tires, load, maintenance, and driving style.

Installation

Complete the tuning first, then remove the emissions hardware. Connect a stable battery charger, use a Windows laptop and the supplied tuning interface to read the factory stock file, provide the required vehicle data, and write the correct calibration to the ECU. After the tune has been successfully flashed, verify that the engine starts and that there are no unexpected diagnostic issues.

Only then remove the factory DPF/DEF/SCR exhaust section, install the 3-inch Turbo-Back Exhaust System, and complete the EGR valve and cooler removal using the supplied block-off plates and hardware. Standard metric sockets, wrenches, extensions, exhaust tools, a lift or suitable jack stands, and penetrating oil are normally sufficient. The current product page estimates approximately 3-5 hours for the complete mechanical installation, with additional time possible for a first-time installer or a truck with corrosion.

An experienced DIY owner can perform the job, but a diesel performance shop can help when tuning, difficult hardware, or existing engine faults make the process more complicated.

Ordering Information

The GMC 2.8 Canyon & Colorado DEF delete kit currently has one product variation to choose before ordering:

Tune Calibration

• Stock Optimized (+0 HP)
• Light Towing (+20 HP)

Confirm that the vehicle is a 2016 Chevrolet Colorado or GMC Canyon Pickup with the 2.8L Duramax LWN. Do not order this configuration for a 2017+ truck simply because the engine displacement is the same.

The store currently lists free U.S. shipping for the kit. Estimated component delivery is approximately 3-4 days for tuning products, 5-6 days for exhaust products, and around 5 days for EGR kits, although parts of a complete bundle may arrive separately.

This product is intended for lawful off road and racing applications. Check applicable emissions regulations before purchase or installation.
