That setup on 0.9bar boost on CIS injection -- 394.3whp/377.9wtq.
The only thing that kept Rick's engine from making more torque and HP was the Euro CIS being maxxed out.
And, with no adjustable WUR, we couldn't (easily) fix the typical 10:1 AFR dip which detracted from the torque.

You have the advantage of having the electronically-controlled frequency valve to correct the AFRs, but you'll ultimately need more fuel. Short of adding a piggyback fuel injector, I anticipate you will need to have your FD set up for max fueling, more than simply adjusting the individual trim screws on the FD.
CIS Flowtech's "007" distributor mod would not apply as that eliminates the frequency valve. You'll have to ask him if he has any other tricks to get more fuel throughput.


Edelweiss Motorsport in Germany can also modify the fuel head, similar to what the factory did on the 934's, including machining the metering slits and piston, but it is very time-consuming and expensive.
We have one of his 934-style modified airflow meter plate assemblies and it is very nice indeed.
They offer all 3 major components -- airflow meter, fuel distributor, and warm-up regulator -- as a complete 934 fueling system for approx. €10k/exchange (plus shipping and associated import fees).
