Did you use the MB airflow sensor, too? 140-160 1974

About the control pressure, I played abit with that device.
In the automotive lab at my uni, they have a huge pile of K-jet stuff. (Mostly new parts.) I used lots of these parts to play with my car.
I actually measure several control pressure units, and the pressure readings when it was fully warm were very much the same. But when the units were cold, there was quite some difference. (I measure 4, from an audi, volvo 244, w123 mb 280E, and one from a w126 500sel) I think that is probably due the the warm-up characterisics of each type of engine.

If you look at the left item (the diaphram looking thing). This thing goes between the control pressure unit and the distributor head on the return side.

Metering head- diaphram thing- control unit- return line.

The diaphram thing seems to also heap enrichment. (But don't know why they made it that way, as the control unit also has vacuum hooked up for enrichment.)
Don't know if that helped much.
