1. A computer-implemented method that, when executed by data processing hardware of a motor vehicle including a turbocharger having a turbine, causes the data processing hardware to perform operations comprising:
receiving an accelerator pedal position input indicating that a vehicle accelerator pedal has moved to an overrun position;
receiving a plurality of vehicle performance parameter inputs each corresponding to a measured vehicle performance parameter, the plurality of vehicle performance parameter inputs including accelerator pedal position, accelerator pedal position rate of change, accelerator pedal position accumulation, brake pedal position, braking force, vehicle lateral force, vehicle longitudinal force, driver selected vehicle mode, engine speed, vehicle speed, and transmission gear selection;
calculating a vehicle dynamic score based on the plurality of vehicle performance parameter inputs;
determining a target boost profile based on the calculated vehicle dynamic score; and
instructing one or more outputs of the vehicle to transition to a dynamic mode to generate an increased turbine power based on the target boost profile.
