Default S2 Fuel Pressure

What is the factory fuel pressure for the 944S2?
Is there a difference between the '89-90 and '91 years given the differernt injectors?

Thanks!

Clark's says all 16V 944s are the same (3.3 bar at idle)

The fuel pressure is 3.8bar.
Check it with the vacuum line off, it should read ~55psi.
