Professional Custom Tuning Support for Your 2017-2019 6.6L L5P Duramax
Unlock the full potential of your 2017-2019 Chevrolet Silverado/GMC Sierra 2500/3500/4500/5500 HD equipped with the 6.6L L5P Duramax engine through our professional AMDP Custom Tuning Support Package. 

Developed by AMDP, Canada's leading diesel tuning specialists, this package provides access to professionally calibrated custom tuning files delivered through the EZ LYNK AutoAgent 3 platform. Whether you're looking for improved drivability, towing performance, or maximum off-road performance, you'll receive tuning designed specifically for your vehicle configuration.
⚠️ Important :
1. This package is a tuning support service only and does not include the EZ LYNK AutoAgent 3 hardware. Don't have an EZ LYNK device yet? → Shop EZ LYNK AutoAgent 3
2. CAN-Bus plugs are required for proper vehicle communication. Purchase them separately → Shop 2017-2019 Duramax L5P CAN-Bus Plugs
3. Heads up for 2017-2018 model years: most of these trucks won't unlock directly through EZ Lynk due to their older ECM bootloader, but once unlocked by another method, they'll flash EZ Lynk files without issue. You have two options: Send your ECM to EZ Lynk for a bench unlock, or unlock it using an HP Tuners unlock box or Power Programmer. Please note that we do not cover the cost of the unlocking.
Available Power Levels
Emissions Level 1 Level 2 Level 3 Level 4 Level 5

Monitoring EGTs on Levels 4 & 5 is highly recommended to prevent excessive heat stress on the engine, turbocharger, and related components.
Why Choose This Package?
✔ Professional AMDP custom tuning

✔ Delivered through the EZ LYNK cloud platform

✔ Shift-On-The-Fly (SOTF) capability will be available in the future.

✔ Multiple power level options

✔ Real-time diagnostics and monitoring through the EZ LYNK platform

*We cannot guarantee the release date of the SOTF feature. SOTF functionality requires a compatible 5-position switch (sold separately).

We also offer an optional transmission tuning add-on, which fine-tunes shift points, line pressure, and torque converter lockup to keep your shifting smoothly and holding up reliably under the added power from your custom ECM tune.
Built on the EZ LYNK Platform
This tuning package utilizes the EZ LYNK AutoAgent 3 platform, allowing calibration files to be delivered electronically without removing or shipping your ECM or TCM.

Once connected, the EZ LYNK system also provides:
  • Wireless tune delivery
  • Vehicle diagnostics
  • Live data monitoring
  • DTC reading and clearing
  • Cloud-based tune management
  • Convenient software updates
Additional Support
If a dash message appears after tuning, we will provide a dash message reset file along with instructions for use. Please contact our support team at cs@enginego.com for assistance.

Certain modifications, such as FASS systems, CP3 conversions, or aftermarket turbo upgrades, require custom tuning built specifically for your truck. If your truck has any of these modifications, please contact us before ordering.
