2014+ 5.3 GM Truck DOD/AFM Delete Package with OEM-Style Camshaft Installation & DOD Tuning Included This package is designed for owners of 2014 and newer GM 5.3L trucks who want to eliminate the factory DOD/AFM (Active Fuel Management) system while maintaining stock-like drivability and reliability. The factory AFM system is known for lifter failures and valvetrain issues over time. Our DOD/AFM delete package converts your engine to a traditional non-AFM valvetrain using a stock-style non-DOD camshaft, providing long-term reliability while keeping smooth idle characteristics and factory-like drivability. This is the perfect option for customers who want to prevent AFM failures without adding an aggressive camshaft.   Must Select Year Service of vehicle for tuning and PCM Unlock
