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.
Manufacturer part number:
READ ALL OF THE INSTRUCTIONS BELOW BEFORE YOU PURCHASE. IT’S TRULY IN YOUR BEST INTEREST.
This code will allow you to complete the “Install Download” process on a Duramax LML 6.6L for the first time. The manufacturer felt that customers who drive this truck should have to pay a premium to use the basic functions of the tuner they purchased. Don’t ask us why, because we don’t know.
Once payment has been processed, your code is instantly displayed on-screen, and you will also receive an e-mail containing a 5 digit pass code to be entered into your tuner.
Once this function is unlocked for use on your 2011+ LML 6.6L Duramax, it should never need to be unlocked again (unless the tuner is reset or is installed onto a different vehicle).
This unlocks the BASIC TUNING function for initial tune download on 2011+ GMC/Chevy Duramax 6.6L LML vehicles ONLY. If you’re looking to release the vehicle lock from your tuner, then purchase the VIN UNLOCK code instead.
DO NOT purchase this code unless your tuner specifically asks for it. If your tuner does not prompt you to enter this code (mentioning part number# 111006) during the first tune download, then you don’t need it.
This unlock code is provided to you INSTANTLY as soon as the payment process has completed. This system is automated, so you will receive your code within 60 seconds - 24 hours a day, 7 days a week, 365 days a year!
