the hooded claw

Can any one tell me if i have a different engine in my94 wagon. The reason is because according to the boost gauge, the turbo is putting out 15psi and holding at 12psi. Not long had the wagon and the only mods i know of are full exhaust, dump valve and k'n cone. Is this normal boost. Can someone please verify as these boxer engines are new to me.

Sounds about right , should hold 0.9 bar at the top end . Guages aren't the accurate .
