Once you have read ALL of the product info BELOW, are ABSOLUTELY THAT SURE YOU ARE BUYING THE PROPER PRODUCT, and are ready to purchase, then please enter the LAST 5 digits of your GMC/Chevy Duramax's VIN number here:
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, you will 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.
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!
