I must have been asleep at the keys last night.

I should have mentioned that the CIS-E system also reduces the control pressure to affect mixture, which reduces the tension on the airflow plate. It just uses a different mechanism to do so - this is the DPR that you measured the miliamps at when tuning your street car.

I believe that is incorrect. I seem to remember that the plunger and plate are controlled by SYSTEM pressure in CIS-E, and not by control pressure as in the slightly older CIS. Yup, verified. See ch. 5, p. 24, Fig. 5-10 of Bosch Fuel Injection and Engine Management, Probst 1989 (Robert Bentley Pub). The so-called "pressure actuator" in CIS-E only controls the fuel flow to the injectors, and this controlled flow cannot affect the force on the plunger or plate. It might be a slightly more accurate way of regulating injector pressure, but it sure takes away one of the greatest tuning features of the older CIS.
