H&S Duramax first tune unlock
Description
H&S XRT Pro, Mini Maxx, and Black Maxx tuners require a first-time unlock code for 2011+ GMC/Chevy Duramax 6.6L LML owners. Only purchase this code if your tuner prompts you for a 5-digit unlock code referencing part# 111006.
Important Instructions for Unlock Code Purchase
Please read the following instructions carefully before purchasing this code—it’s in your best interest!
This code enables the “Install Download” process for the first-time setup of a 2011+ Duramax LML 6.6L. Unfortunately, the manufacturer requires an additional fee for owners of this specific truck to access the basic functions of their tuner. Why? We don’t know either.
How It Works
- After your payment is processed, your code will be instantly displayed on-screen and emailed to you.
- This 5-digit passcode must be entered into your tuner when prompted. Once unlocked, this function will remain active for your Duramax unless the tuner is reset or installed on another vehicle.
What This Unlocks
- The BASIC TUNING function for the initial tune installation on 2011+ GMC/Chevy Duramax 6.6L LML vehicles only.
- If you need to remove the vehicle lock from your tuner, you’ll need to purchase the VIN UNLOCK code instead.
Important Notes
- DO NOT purchase this code unless your tuner specifically prompts you for it. During the first tune download, your tuner will mention part number #111006 if this code is required. If you don’t see this prompt, you don’t need the code.
- Keep your unlock code safe—it’s tied to your tuner and will only be needed again if the tuner is reset or used on another vehicle.
By following these steps, you’ll ensure a hassle-free setup for your Duramax. If you have questions, feel free to reach out before making your purchase!
