Product Information
Product Description
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.
STAGE 1 | TRICERATOPS
Entry-Level Full Delete Kit
The Triceratops Stage is the foundation. It includes the core components required for a proper delete—simple, effective, and designed to get your truck fully deleted without additional upgrades.
If you want Switch-On-The-Fly (SOTF) capability and expanded hardware, step up to Stage 2 or Stage 3.
Stage 1 Includes:
- EFI Live tuner
- Single delete tune (Tow tune sent by default if not specified)
- EGR delete kit
- DPF delete pipes
STAGE 2 | VELOCIRAPTOR
Value Delete Kit (Balanced Performance)
The Velociraptor Stage is the most popular middle ground—adding SOTF control and key hardware upgrades for a more capable setup that balances power, control, and reliability.

- EFI Live tuner
- SOTF tuning support package
- SOTF switch (Switch-On-The-Fly)

🦖 STAGE 3 | T-REX
Ultimate Delete Kit (Maximum Capability)
The T-REX Stage is the all-in solution—designed for owners who want full SOTF capability, complete turbo-side support, intake and downpipe upgrades, and lifetime tuning support. This is the most comprehensive Dyno Diesels package for the LML platform.
Stage 3 Includes:
- EFI Live tuner
- SOTF tuning support package
- SOTF switch (Switch-On-The-Fly)
- EGR delete kit
- Passenger-side up-pipe

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
