{"product_id":"6-6l-duramax-l5p-dpf-egr-def-delete-kit-with-obd2-flash-tuning","title":"6.6L Duramax L5P DPF EGR DEF Delete Kit with OBD2 Flash Tuning","description":"The SPETUNER #11307 is a complete delete kit designed to remove restrictive emissions systems from 2017-2023 6.6L Duramax L5P engines, providing significant performance enhancements for off-highway and competition use. This kit addresses common issues by eliminating the Exhaust Gas Recirculation (EGR) system to prevent soot buildup and carbon accumulation, and replaces the Diesel Particulate Filter (DPF) while bypassing the Diesel Exhaust Fluid (DEF) system. This not only leads to improved exhaust velocity and lower Exhaust Gas Temperatures (EGTs) but also reduces maintenance costs associated with clogged DPFs and DEF system failures.\n\nAt the core of the system is the OBD2 Flash Tuning Interface with an Unlock Tool, which allows for direct ECM calibration without needing to swap the physical ECM. This interface comes with preloaded performance tunes offering selectable power levels ranging from 0HP up to +150HP. The kit also includes options for custom exhaust configurations, including 4\" or 5\" downpipe-back systems, with choices for mufflers or dual-exit setups to fine-tune sound and performance.\n\nThe benefits extend beyond raw power, offering improved fuel economy through reduced backpressure and better combustion, as well as lower maintenance costs by eliminating the need for DPF and DEF refills and sensor replacements. Additionally, the removal of EGR and DPF components helps in achieving cooler engine and turbo operating temperatures, potentially increasing the longevity of the engine and turbocharger.\n\nThis kit is specifically designed for 2017–2023 Chevrolet Silverado 2500\/3500 HD and 2017–2023 GMC Sierra 2500\/3500 HD models equipped with the 6.6L L5P Duramax engine. It is important to note that the DPF Delete Pipe configurations differ between 2017–2019 and 2020–2023 model years, requiring the correct option to be selected. Furthermore, this kit is explicitly stated to not fit Cab \u0026amp; Chassis models. While basic mechanical skills are sufficient for installation with provided step-by-step guides and video tutorials, professional installation is recommended for the exhaust system components. This product is intended for off-road and competition use only and is not legal for street use in emissions-regulated areas.","brand":"SPETUNER","offers":[{"title":"Default Title","offer_id":52866386231608,"sku":"#11307","price":3166.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687688032.webp?v=1787906977","url":"https:\/\/store.motormia.co\/products\/6-6l-duramax-l5p-dpf-egr-def-delete-kit-with-obd2-flash-tuning","provider":"MOTORMIA","version":"1.0","type":"link"}
