An exhaust gas recirculation (EGR) system for an engine with a variable geometry turbocharger ( ) incorporates a master rotary electric actuator (REA) ( ) with a microprocessor controller ( ) receiving condition signals ( ) from sensors ( ) associated with the turbocharger and the engine control unit (ECU) ( ) and positioning the turbine inlet nozzle ( ) geometry of the turbocharger in response to a predetermined matrix of the condition signals. A slave REA ( ) is connected through an internal processing unit ( ) to the controller to position an EGR valve ( ). The processing unit provides an actual position signal to the controller which responds with a desired position signal based on the predetermined condition signal matrix. The processing unit engages the slave REA to position the EGR valve.
