Systems and methods are provided for engine systems including a first multiple tap aspirator with a motive inlet coupled to an intake upstream of an air induction system throttle and a mixed flow outlet coupled to an intake manifold, and a second multiple tap aspirator with a motive inlet coupled to the intake upstream of a main throttle and a mixed flow outlet coupled to the intake downstream of the air induction system throttle. During non-boost conditions, intake air may be selectably diverted around a compressor and through the first and/or second aspirator based on desired vacuum generation. During boost conditions, the first and second aspirators may function as compressor bypass valves, and intake air may be selectably directed from downstream of the compressor to upstream of the compressor via the first and/or second aspirator based on a desired compressor bypass flow.
