A method for coordinating control of exhaust gas recirculation ( 18 ) in a turbocharged internal combustion engine ( 10 ) with control of engine boost. When actual boost deviates from a desired boost set-point developed by a boost control strategy ( 32 ), such as during a sudden acceleration or deceleration, the EGR control strategy ( 34 ) provides a prompt adjustment of exhaust gas recirculation (EGR) seeking to null out the boost disparity.
