DPF/EGR/DEF Delete Kit with Tuner

The Spelab DPF/EGR/DEF Delete All-in-One Kit is engineered for 2017-2023 L5P 6.6L Duramax GMC Sierra and Chevrolet Silverado 2500/3500 HD trucks. This comprehensive package includes an EGR delete kit, DPF delete kit, and a DEF delete/tuner delete with an OBDII Flash Delete Tuning Interface. The kit's primary goal is to maximize performance by removing restrictive DPF and EGR systems, leading to unrestricted airflow and lower engine temperatures. The included tuner optimizes fueling, turbo response, and transmission shifting, offering substantial gains in horsepower (50HP-150HP+) and torque. Furthermore, it aims to improve fuel economy by 2-5+ MPG by eliminating forced regens and DEF usage, while also enhancing reliability by reducing carbon buildup and turbo backpressure for extended engine life. Key components include the EGR Delete Kit to reduce carbon buildup, the DPF Delete Kit to increase exhaust flow and power, and the OBDII Flash Delete Tuning Interface which allows for customizable performance parameters and seamless tuning adjustments. SOTF tuning is supported, utilizing factory steering wheel controls for on-the-fly power level changes. The kit is intended for off-road or competition use only. Professional installation is recommended to ensure proper setup and optimal performance, although detailed installation guides for the EGR Valve Cooler Delete Kit and DPF Race Pipe Delete are provided. Compatibility is specific to the 2017-2023 L5P 6.6L Duramax Diesel GMC Sierra 2500/3500 HD and Chevrolet Silverado 2500/3500 HD. It is crucial to note that this kit is not compatible with cab and chassis models. Additionally, the Spelab 6.6L Duramax L5P DP-Back exhaust system must be used in conjunction with their specific downpipe, as the factory downpipe features an integrated SCR assembly that prevents direct connection. The manufacturer also advises that installing this kit may void the vehicle's warranty, and recommends consulting with the vehicle manufacturer or dealer prior to installation.
