EFI Live Tuning Package

Pre-Loaded & Ready to Flash | Dyno-Validated Calibration

This EFI Live tuning package for 2001–2016 Chevy/GMC Duramax trucks ships pre-loaded and ready to go, eliminating setup delays and guesswork. All calibrations are professionally developed using a dyno-first tuning process, focused on controlled power delivery, drivability, and long-term reliability.

The tuning included in this package is built by Stealth Diesel, a well-established EFI Live calibrator with extensive experience dating back to the early days of the EFI Live platform. These are not generic or recycled files—each tune is designed to work with real-world Duramax configurations.

Dyno-Built EFI Live Calibration

Proper EFI Live tuning allows full control over:

• Fueling and timing strategy
• Boost and torque management
• Throttle response and drivability
• Transmission behavior (where applicable)

The result is usable power, smoother operation, and tuning that works with your hardware—not against it.

Build the Exact Kit You Need

Use the drop-down menus to configure the tuning package that matches:

• Your engine generation (LB7, LLY, LBZ, LMM, LML)
• Your transmission
• Your intended use (daily driving, towing, performance)

This ensures the tuning is appropriate for your truck—not a one-size-fits-all approach.

Why Pre-Loaded Matters

With pre-loaded EFI Live tuning:

• No waiting for files after delivery
• No laptop setup required to get started
• Flash and drive with confidence

This is ideal for customers who want a straightforward, professional solution without unnecessary complexity.

Avoid Generic “Canned” Tunes

Preloaded factory or low-quality aftermarket tunes may work for basic use, but they often lack refinement and consistency. Dyno-validated EFI Live tuning is developed using measured data, testing, and calibration refinement—not guesswork or copy-paste files.

Dyno Diesels Tuning Philosophy

Dyno Diesels focuses on proper calibration, measured results, and reliable performance. Every tuning package is selected to deliver predictable power, clean drivability, and long-term durability across the entire Duramax lineup.
