Spec is 0.75-0.85 bar, I believe (10-12psi). On my 1984 300D, there was no increase in power beyond 10psi... same power with 10psi as there was with 17psi. You need more fuel to make more power. But, if you are under 10psi, either the wastegate is opening too soon, or the IP is way low on fuel delivery (ALDA adjustment needed).
