You just kicked the problem straight out of the ballpark, which is respectable for sure, and often times cost effective on an individual build basis. R&D for a single car project can be more hassle than just going the route you did and washing your hands of any potential problem areas.
But it will be interesting to see what F.I. may find as to sources of the restrictions. Naturally, a full twin pump with rails kit may be cost prohibitive for many customers. So there should be some value in finding this information.
I have had intentions of building a full custom test bench for this stuff. I need to find an electrical engineer who can help me with a schematic on a custom injector driver with adjustable power source output, realistic firing order/sequence for 4 6 and 8 cylinders, adjustable simulated RPM, and pulsewidth. Anybody? Bueller?
