Full Delete Kit DPF/EGR/DEF | GM/Chevy 6.6L L5P Duramax | 2024–2025

Release your 2024–2025 Duramax's full capabilities with this comprehensive DPF, EGR, and DEF removal package engineered specifically for the newest L5P platform. This complete bundle delivers everything required for total emissions system elimination — featuring ECU unlocking components, tuning authorization credits, EGR removal hardware, and multiple exhaust configuration options.

Critical Information: Current 2024–2025 ECU security protocols limit calibration availability to a single tune file (factory power specification) following the control module unlock procedure. This configuration ensures complete emissions system removal while preserving original horsepower and torque output.

ECM unlocking must be performed by HP Tuners before calibration installation. Customer bears responsibility for shipping the control module. (Unlocking service is not included)
