A method as claimed in claim 1, wherein the selected engine operating parameter is the fuel injection rate setting. 7. A method as claimed in claim 1, wherein the selected engine operating parameter is the fuel injection pressure setting. 8. A control system for controlling up-shifting of a vehicular powertrain system using a turbocharged internal combustion engine operating in a maximum foot pedal position and in an associate full-load condition, the powertrain system including a multiple speed change-gear transmission and a control unit for controlling both the engine and the transmission, the control unit having logic rules effective for: establishing that an up-shift is about to occur from a first gear to a second gear; upon establishing that an up-shift is about to occur, placing the engine in a transient shift operating mode which includes the steps of: reducing a magnitude of at least one of the engine speed and the engine torque to enable shifting from the first gear, and modulating a selected engine operating parameter to maintain the boost pressure by at least one of increasing the exhaust energy and maintaining the rotational speed of the turbocharger while the magnitude of the at least one of the engine speed and the engine torque is reduced, the selected engine operating parameter being chosen from a plurality of parameters including: fuel injection timing, fuel injection rate, fuel injection pressure, turbocharger wastegate controller valve setting, intake air throttle setting, variable geometry turbocharger vane position setting, engine valve timing setting, engine valve activation state; establishing that the shift from the first gear has been completed; upon establishing that the shift from the first gear has been completed: returning the engine to full load-condition, while also immediately modulating the selected engine operating parameter so as to increase the torque output of the engine, and coordinating the modulation of the selected engine parameter with the shifting of the transmission to at least one of: decrease the turbocharger lag associated with shifting and to thereby decrease a power output response time of the engine, and reduce exhaust emissions during shifting events. 9. A system is claimed in claim 8, further comprising the step of executing the shift from the first gear to the second gear using a shift actuator responsive to a control signal from the controller. 10. A system as claimed in claim 8, wherein the selected engine operating parameter is the vane position setting. 11. A system as claimed in claim 8, wherein the selected engine operating parameter is the turbocharger wastegate controller valve setting. 12. A system as claimed in claim 8, wherein the selected engine operating parameter is the fuel injection timing setting. 13. A system as claimed in claim 8, wherein the selected engine operating parameter is the fuel injection rate setting. 14. A system as claimed in claim 8, wherein the selected engine operating parameter is the fuel injection pressure setting.
