TSP 2019+ LT DOD Hole Plugs

GM released the new Dynamic Fuel Management (DFM) in the 2019+ full size trucks and SUV's for the 5.3 and 6.2L engines (not found in the 4.3L or the 6.6L L8T). Since these oil control manifolds are in the valley of the block and no longer a part of the valley cover itself, the old delete methods (delete cover or plugs) no longer work.

These are simple yet effective as you remove the old DFM control valves, wiring harness and plug that sticks through the valley cover and install these delete plugs as well as the bulkhead plug in the valley cover itself.

Please note: Computer tuning IS required to complete this modification. You must have DOD/AFM disabled in the PCM to prevent the Engine Control Module from setting DTC Codes.
