The way I read it, both codes are telling you the same thing.
The ECU is commanding a set boost through the PWM signal that it is sending to the modulator valve, but it (the ECU) is not "seeing" the required result as far as the feedback sensor goes (boost pressure sensor).
Hope I am not "teaching you to suck eggs"
