Unleash the True Power of Your Duramax

Take full control of your 2001-2010 Chevy or GMC with the EFI LIVE Chevy/GMC Duramax Support Package. Unlike standard, off-the-shelf files, this package delivers true custom tuning engineered specifically for your truck's unique modifications, tire size, and daily usage—whether you are setting up a heavy-duty tow rig or maximizing street performance.

Key Features & Customization:

• Purpose-Built Tuning: Files are written specifically for what you are doing with your truck, ensuring optimal torque and efficiency.
• Broad Compatibility: Supports 2001–2010 Duramax platforms, including LB7, LLY, LBZ, and LMM.
• Hardware Flexibility: Use your existing EFILive AutoCal/Flashscan or EZLYNK, or bundle a brand new Autocal V3 or EZLYNK device directly with your order.
• Performance Add-Ons: Dial in your build with optional Transmission Tuning and a custom RPM Limiter (choose between Stock/Safe or Hard Cut).

Important Technical Notes:

• An EFILive AutoCal or Flashscan device is required to flash these tunes onto your truck.
• A stock read file is strictly required for all Cab & Chassis, Topkick/Kodiak, Van, and LB7 models.
