Complete calibration package for the 2004.5–2007 LLY/LBZ 6.6L Duramax paired with the Allison 1000 — a coordinated engine and transmission tune for the mid-generation classic body style.
What's included
- Custom VIN-matched LLY or LBZ engine calibration with multiple switchable power levels
- Allison 1000 TCM calibration covering shift pressure, shift timing, and torque converter management
- Datalogging support for post-install refinement
How it works
Files are delivered via EFI Live FlashScan V2. Your calibration is built from your stock ECM/TCM files and locked to your VIN. A FlashScan V2 device is required to flash both controllers.
Support tiers
- Limited (4 Weeks): Four weeks of revision rounds; tune stays on your tool after the window closes.
- Full (Lifetime): Unlimited revisions and lifetime access as your build evolves.
Requires an EFI Live FlashScan V2 device. Specify LLY or LBZ at time of order.
Calibrations are developed for motorsport and off-road use. Verify local regulations before use on public roads.
