What is better than a detailed write up? A detailed video This is a multi part, step-by-step series where we are fully deleting the Active Fuel Management (AFM) / Displacement on Demand (DOD) system from my 2014 Silverado with the 5.3L. This process is the same for most Silverados, Sierras, Tahoes, Yukons, and Suburbans made after 2006. Note that Parts 5C - 9 are still being filmed and edited and this will be updated as they become available Try anything shown in these videos at your own risk - we are not professional mechanics and this is only designed to be a helpful reference, not a how to guide - always check with a certified mechanic before doing any work on your vehicle and make sure you are working in a safe environment AFM DOD Delete Part 1 - 2014 Silverado 5.3L Baseline Dyno - How Much Power Does It Make? In this Video we are cover the baseline dyno numbers my truck made before modifying the vehicle. We will re-dyno the truck after adding the stage 1 Cam and ported heads from GPI. Once we know how much more power is made with those modifications, we will be adding the 6.2L intake manifold, throttle body, and AirRaid air intake and dynoing the truck again to see how much additional power is made. Note that we ran into some issues with the dyno run that we weren't expecting simply due to our lack of knowledge of the automatic transmission in 2014 Silverado. The dyno run was conducted from 1st through 3rd. Unfortunately, I have not yet received any additional Dyno graphs of my run except for the one shown in the video. My Truck made an a Max HP at the wheels of 333 HP and 364 Torque in 3rd Gear. Due to transmission gearing and the rear in the vehicle, My numbers are likely around 30HP higher than they should be. It is also important to note that the vehicle is factory limited to 95MPH. From the research I have done it appears this is put in place to protect the driveshaft. Here is another run that was shared with me that shows the full first through third pull on a 5.3 and should be useful for comparison: AFM DOD Delete Part 2 - 2014 Silverado 5.3L L83 - What Parts Do You Need? All of the parts for the AFM delete were purchased from Gwatney Performance Innovations (GPI) - NOT A SPONSORED VIDEO SERIES - ALL PARTS WERE PURCHASED. 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.
