2011–2016 Chevy / GMC Duramax 6.6L

Dyno Diesels Stage 1, Stage 2 & Stage 3 Delete Kits

Dyno-Engineered Systems. Proven EFI Live Control.

Dyno Diesels delete kits for the 2011–2016 Duramax (LML) are engineered as complete, matched systems—combining EFI Live tuning with the correct EGR, exhaust, and turbo-side hardware to deliver reliable off-road performance, clean drivability, and long-term durability.

All tuning is built on the EFI Live platform by an experienced calibrator with long-standing Duramax development history. These are vehicle-specific files, designed to work with the included hardware and your truck’s configuration—not generic or “canned” tunes.

Tuning & System Design Philosophy

Dyno Diesels kits are built with a dyno-first, system-balance mindset:

• Exhaust flow, turbo drive pressure, and intake air all work together
• Tuning is matched to the hardware—not forced to compensate for weak parts
• SOTF control allows real-time adjustment for tow, street, or performance use

The result is predictable power, cleaner drivability, and dependable operation in off-road and competition environments.

Important Notes

• Aftermarket tuning is required for all delete configurations
• SOTF functionality requires the included switch (Stages 2 & 3)
• Professional installation recommended for up-pipes and downpipe components
