Because of the torque control protocol in the computer. Throttle opening is not directly corresponding to your gas pedal. All of the sensors are constantly providing feedback to the computer. The computer then commands an acceptable throttle opening and allowable boost pressure. It can reduce the psi up or down regardless of where your right foot is. Welcome to Big Brother. You can massage some of this out with a custom tune.
