Max boost on stock turbo?
 

Planning to raise the boost / fuel soon.

Car is a late intercooled 940. How far before the turbo becomes out of its efficiency range?

I think 15-18psi would be fine, you could always put in a air temp gauge to monitor the outlet temp. of the compressor.
I actually think the compressor is able to flow enough air to max out the Injection pump with a good inter-cooler, but not sure I have not tried it myself. Yet.

Chris, are you running the standard fibre head gasket, or the MLS steel one?

I'm running 16psi on mine but also have the MLS.

Standard Ian... for now ;)
