DPF DEF EGR Delete Kit with EZ Lynk Tuner

The Spelab All-in-One Delete Kit is engineered for off-road and competition builds on 2017-2023 6.6L Duramax L5P Chevrolet Silverado and GMC Sierra 2500HD/3500HD trucks. This comprehensive package integrates a T409 DPF Delete Pipe, EGR Delete Kit, and an EZ Lynk tuner with Switch-On-The-Fly (SOTF) tunes, designed to overcome common factory restrictions and unlock the engine's full potential. The kit eliminates DPF and EGR issues, preventing forced regenerations and power limiting while reducing engine temperatures and intake carbon buildup for improved long-term reliability. The included EZ Lynk device with SOTF tunes allows for instant switching between power levels such as Economy, Tow, and Performance, enhancing drivability, fuel efficiency, and delivering significant horsepower gains. Users can expect improved throttle response, lower exhaust temperatures, a more robust exhaust sound, reduced vehicle weight, and the elimination of future DPF/EGR repair costs. Installation requires an EZ Lynk tuner, which connects to the truck's OBD2 port and interfaces with the EZ Lynk mobile app via Wi-Fi for a 60-second setup. The tuner also functions as an advanced diagnostic scan tool, enabling reading and clearing of DTCs and over-the-air firmware updates. Tune management is handled through the EZ Lynk cloud interface, allowing for easy access and installation of tune files, with automatic data sync for VIN-locked tuning. Important fitment and installation notes apply: All tunes are custom and non-refundable. EZ LYNK tuning files require 7–10 business days to create, so do not install delete parts early. This kit does not include a TCM Tune or SOTF Switch. For 2017-2018 L5P models, a GM E41 ECM unlock service or an unlocked ECM is required before tuning. If your 2017-2019 vehicle has a white CAN bus plug, you must select the white CAN bus plug option. The product does not fit Cab & Chassis trucks and is intended for off-road or race use only, as disabling emissions equipment may violate local regulations. Users should be aware that PTO units are excluded.
