This is the second part of a multi part series where we will be fully deleting the Active Fuel Management (AFM) / Displacement on Demand (DOD) system from my 2014 Silverado with the 5.3L L83 motor. This process is the same for most Silverados, Sierras, Tahoes, Yukons, and Suburbans made after 2006. In this video we are going to cover the parts needed to delete the AFM system. All of the parts for the AFM delete were purchased from Gwatney Performance Innovations (GPI). The components for deleting AFM are listed below in this description. Since much of the motor is being disassembled for this process, I also decided to upgrade some of the other components such as ported heads, 6.2 L86 intake manifold, throttle body, and an airaid air intake. In part three of this series we will be showing how to remove the motor from my Silverado.
