Radar, Your outside ambient temp is 29F (was snowing)? The ECU is measuring air mass, cold air , cold humid dense air will allow the engine to make the rated power output with less boost pressure. The boost pressure reading is not a constant. The engine will always produce the power output with timing and then govern/drop boost when the power output is met.
