In one example, a method may include in response to a tip-out following a tip-in, when an exhaust catalyst temperature is within a threshold range, deactivating fuel injectors to the engine and increasing air flow to an exhaust turbine based on a desired increase in a turbine speed to maintain the turbine speed at or above a threshold speed.
