EZ LYNK Duramax Tuning Platform Overview
The EZ LYNK Duramax package delivers a streamlined, cloud-connected solution for tuning and diagnostics on 2007.5–2023 GM Duramax trucks. Through the Ez Lynk, you can manage performance, monitor data and receive technician support remotely—no cables required.
How the EZ LYNK Duramax Package Works
The Auto Agent 3 connects to your truck’s OBD2 port and links with the EZ LYNK app, giving your technician direct access for updates, troubleshooting and tune delivery via Wi-Fi.
Important for 2017–2023 L5P Owners
These model years use Switch-On-The-Fly (SOTF) tuning controlled directly through your factory steering-wheel buttons. Because switching is handled electronically by the truck, no external switch is required or included—resulting in a cleaner, factory-style setup with full functionality.
NOTE: Tuning does not support PTO units.

1. Shipping Address Guidelines
To minimize costs and ensure smooth delivery, follow these tips when providing your address:
- Accuracy: Double-check your shipping address for errors before placing an order.
- Residential vs. Business Classification: If your business operates from a residential location, it will be classified as a residential address, and delivery fees will be charged accordingly.
- Contact Information: Provide an accurate phone number. Carriers may need to reach you to verify delivery details—failure to do so could cause delays.
2. Multiple Items Shipment
We ship orders as items become available, so you may receive multiple shipments for a single order.No additional shipping fees will be chargedfor these separate shipments.
3. Shipping Partners
We collaborate with leading carriers including USPS, UPS, FedEx, DHL, and Amazon Logistics. We prioritize shipping from the nearest warehouse (U.S. or Hong Kong facilities) to your location. While most orders are delivered within5–15 business days, inventory availability varies—items shipped directly from manufacturers or requiring transfer may take longer.
