Abstract: A system for optimizing engine braking power is provided. The system includes an intake manifold configured to receive air from a compressed air source. The system includes an engine brake associated with a power source. The system also includes a bleed valve configured to bleed a portion of the air from the intake manifold. The system further includes a controller in communication with the bleed valve and configured to receive a status of the engine brake. The controller is configured to activate the bleed valve to bleed a portion of the air from the intake manifold based at least in part on the engine brake being active and based at least in part on a pre-determined relationship between an air pressure in the intake manifold and one or more parameters associated with the power source.
