The actual boost target in the ECU is 0.94 bar (13.6psi) up to 5000rpm then tapering off to 0.67 by 6200.

The boost dynamics are normally set to run the actual boost just below the target, and as Tony says yours is running a little over - or suffering a little bit of overshoot by the sound of things. A full or partial decat, or some oil in the boost control pipework could easily explain it. At that level it shouldn't be anythign to worry about provided the engine is otherwise in good nick.
