description A system for controlling boost pressure at various different altitudes of operation of a turbo charged internal combustion engine includes a wastegate valve, an actuator, and a controller. Signals delivered from an engine speed sensor, a boost pressure transducer, a barometric pressure sensor, and a turbocharger speed sensor are processed in the controller. A control signal delivered from the controller to the actuator controls the position of the wastegate valve, bypass of exhaust gasses, and the speed of the turbocharger. The controller is configured to compare the turbocharger speed to a predetermined threshold value and determine the control signal based on the comparison.
