930 rich running fuel pressure

We are out of ideas. This 1978 930 has had 3 different regulators all set to factory specs. The last one was set up to adjust for the ever changing fuel pressure. After a short drive the car starts running very rich. We checked the flapper and cleaned and set all the recommended devices according to the factory manual that was published in 1970s. Any further developments since then? Has euro injection,Twin plug heads 1 bar boost etc. and generally use 108 octane leaded fuel. One good thing is no worries of burnt pistons.
