Good brainstorming going on. Also good thoughts on the next issue (setting AFR's) after I get the flow issue resolved.

For 79 SC
Control Pressure Warm - 3.2-3.6 bar (vacuum line attached) and 2.7-3.1 bar (vacuum line removed).

Here is another thought. Without the injectors in place the FD can flow more than enough fuel; thus, the limit is caused by the injectors. Is there a different injector other than the SC injector that will flow more? In particular, the 930 CIS injectors at over $100 a pop (930-110-225-02-M14, 930-110-225-00-M14) vs the SC's (911-110-225-01-M14) at $35 each. Anyone tested different CIS injectors? What about Volvo/Audi/Mercedes/Saab/VW?

My injectors are Bosch 0 437 502 004

Another good calculator of HP for a given injector, calculating injection in lb/hr to cc/min, and determining flow rate when you increase the pressure:

Here are links on flow rates for different injectors. Unfortunately for me, they are for EFI injectors only with no data for CIS.
