By eliminating these systems, the kit allows for improved exhaust flow and reduced engine temperatures. The EZ Lynk Auto Agent 3 tuner provides a user-friendly interface to adjust power levels and monitor engine performance, making it a complete solution for diesel trucks enthusiasts. This LML Duramax delete kit is perfect for those wanting to upgrade and improve their vehicle.

Features

EZ Lynk offers wireless tune delivery, remote calibration revisions, data logging, diagnostic functions, and live vehicle monitoring through a mobile device. The tuner is linked to the supported vehicle and allows the tune provider to update files without shipping a handheld programmer back to the shop. Multiple pipe and muffler options make the bundle adaptable to different exhaust and sound preferences. The complete hardware-and-tuning solution is designed to improve serviceability and support reliable operation when the engine and transmission are properly maintained. 

Tuning & Settings

EZ Lynk Auto Agent 3 – This tuner uses a cloud-based interface and OBD2 connection to provide seamless tuning and monitoring capabilities. It supports SOTF (Shift-On-The-Fly) adjustments and includes multiple power levels, allowing users to optimize performance based on their specific needs.

Tune Level HP Increase Best For
Stock 0 HP Factory-like operation
Level 1 up to +50 HP Daily driving and towing
Level 2 up to +100 HP Balanced performance
Level 3 up to +150 HP Aggressive street use
Level 4 up to +200 HP Maximum off-road performance

Actual output depends on engine condition, transmission, fuel modifications, turbo setup, elevation, and supporting components. 

Characteristic Expected Effect Important Note
Fuel Efficiency May improve during steady driving No fixed percentage is guaranteed
Towing Response Additional torque may improve response under load Factory towing and payload limits do not change
Exhaust Flow Reduced restriction through the selected pipe system Depends on the chosen 4-inch or 5-inch configuration
Monitoring Live supported parameters through the mobile application Auto Agent 3 must remain connected for monitoring
Return to Stock Possible when the original stock file is available Factory hardware must also be restored
Tune Support 4-week or unlimited access Depends on the option purchased

Optional Add-Ons

  • 4-inch Exhaust System – Offers a balance of performance and sound.
  • 5-inch Exhaust System – Provides maximum flow and aggressive sound.
  • No-Muffler Option – For ultimate exhaust flow and sound.
  • With-Muffler Option – For a quieter exhaust note with improved flow.

Key Benefits

  • Selectable Power Levels – Provides multiple tune settings from stock output up to +200 HP for supported applications.
  • Vehicle-Specific Tuning – ECU profiles are generated using the supplied VIN and vehicle configuration.
  • Cloud-Based Access – Tune files and supported revisions are delivered through the EZ Lynk mobile platform.
  • Reduced Exhaust Restriction – The selected pipe system replaces the applicable factory aftertreatment section.
  • Flexible Product Configuration – Choose the preferred exhaust diameter, muffler setup, and tuning-support package.
  • Potential Efficiency Benefits – Fuel efficiency may improve under suitable driving conditions, but no fixed gain is guaranteed.
  • Simplified Emissions-System Layout – Removing supported aftertreatment components may reduce dependence on failure-prone emissions hardware, although overall reliability still depends on maintenance and tune selection.

Installation Information

A detailed installation guide is included with the kit. Customers with basic mechanical experience can complete the installation themselves, although professional installation is recommended for those unfamiliar with diesel exhaust, EGR, and electronic tuning systems.

Before tune files can be generated, you will need to provide:

  • VIN Number.
  • Transmission Type (Automatic or Manual).
  • 2WD or 4WD configuration.
  • Turbocharger information.
  • Fuel-system modifications.

Recommended tools:

  • Standard metric sockets and wrenches.
  • Torque wrench.
  • Safe lifting equipment.
  • Penetrating lubricant.
  • Suitable exhaust tools.
  • Coolant drain container.
  • Battery charger or maintainer.

Typical installation time:

  • EZ Lynk programming: approximately 20-40 minutes (after the correct tune files have been generated)
  • Mechanical installation: approximately 4-6 hours

Tuning is performed through the EZ Lynk mobile application using a compatible smartphone connected to the Auto Agent 3 via Wi-Fi. A stable internet connection and battery voltage are required throughout the programming process.

No More Emissions Codes

After the correct hardware configuration and vehicle-specific tune are installed, the calibration is designed to address supported monitoring routines associated with the removed DPF, DEF, SCR, and EGR systems. 

Exact code coverage depends on the ECM operating system and supplied tune files. Tuning does not repair damaged wiring, failed sensors, coolant leaks, turbocharger faults, or unrelated engine problems.
