What’s Included in the Spetuner L5P Duramax Delete Kit?
✔️L5P EGR Delete Kit

Technical Function: Replaces the Diesel Particulate Filter (DPF) and bypasses the Diesel Exhaust Fluid (DEF) system.
Core Benefit: Enhances exhaust velocity and lowers Exhaust Gas Temperatures (EGTs). This modular upgrade reduces maintenance costs by eliminating common sensor failures and DEF-related downtime.
✔️OBD2 Flash Tuning Interface & Unlock Tool
Technical Function: Provides direct ECM calibration via the OBD2 port without requiring a physical ECM swap.
Core Benefit: Includes preloaded performance tunes ranging from 0HP to +150HP. The integrated unlock tool simplifies the installation process by eliminating the need for crank relearn or core returns.

Technical Function: Modular exhaust upgrades including 4" or 5" downpipe-back systems.
Core Benefit: Available with optional mufflers or dual-exit configurations, allowing for precise control over exhaust sound, backpressure reduction, and aesthetics.
