AMDP Custom Tuning for 2020-2023 L5P Duramax with EZ Lynk AutoAgent

This package comes with an EZ LYNK AutoAgent 3 device.

Unlock the full potential of your 2020-2023 Chevrolet Silverado or GMC Sierra equipped with the 6.6L L5P Duramax engine using AMDP's premium custom tuning delivered via the industry-leading EZ Lynk AutoAgent device. Our expertly crafted tunes deliver enhanced horsepower, torque, throttle response, and drivability while maintaining reliability for daily driving, towing, or performance applications.

Key Features:

Custom-Calibrated Power Levels: Single power level tunes optimized for your specific setup, with shift-on-the-fly (SOTF) capability coming soon for seamless on-the-go adjustments.

Cloud-Based Instant Tuning Library Access: Enjoy immediate access to AMDP's full library of tunes directly through the EZ Lynk cloud platform—no waiting for file deliveries.
Cab & Chassis Supported: Full compatibility for both pickup and cab & chassis models (excluding Kodiak/International L5D trucks).

Transmission Tuning (T93):

AMDP now offers custom transmission tuning for T93 (2020-2023 models) controllers. This optimizes shift points, torque management, line pressure, and overall drivability for smoother, firmer shifts and better performance under load. Unlocking and flashing are conveniently handled directly through the OBD port using your EZ Lynk AutoAgent device—no additional hardware required.

Requirements:
To install and use AMDP Custom Tuning with EZ Lynk, the following items are required:

EZ Lynk AutoAgent 3 device
Compatible smartphone (iOS or Android) with the EZ Lynk app installed
CAN-Bus plugs (required for proper vehicle communication)

Support Package Options:

Limited Support Package: Gain full access to all available tunes for 4 weeks. After this period, any tunes already installed on your vehicle will remain functional. Easily upgrade to Full Support at any time while your vehicle remains supported.

Full Support Package: Unlimited access to all tunes and future updates for as long as we support the L5P platform.

Instructions:

Step 1: Purchase this support pack product for your desired time frame

Step 2: If you have a shop level scan tool, fill the DEF tank and perform a DEF level reset. We always prefer to have the dash clear before flashing but if that is not possible then we can deal with it after flashing

Step 3: Plug the Ezlynk device into the vehicle and a prompt asking you to accept an autolink from AMDP Custom Tuning will appear. Click "Accept"

Step 4:  Flash your desired tune into the vehicle and ensure you click select a file from the folder that matches the current model year that EZlynk displays as your model year. 

Additional Support:

If you encounter dashboard messages post-tuning, email support

For modified trucks (e.g., FASS fuel systems, CP3 conversions, aftermarket turbos), contact us via email for fully custom-built tunes if you do not see anything autoshared for your application.
