Abstract
A control system and method that compensates for changes in backpressure of an engine includes a pressure sensor that senses the backpressure. A boost compensation module that communicates with the pressure sensor, determines an averaged BC factor, and adjusts a variable geometry turbo based on the averaged BC factor.
