Some aftermarket engine management systems can control 16 injectors. We did a roughly 1500 hp 540 BBC engine using BigStuff3 EFI and had 8 primary and 8 secondary injectors (again in a custom fabricated manifold). In this application we also staggered the injector operation so that we were not using the secondary 8 injectors except at higher boost levels when the first 8 were near maximum duty cycle. The BigStuff3 software allows you to adjust how the two sets of injectors are controlled. In this application we also had the fuel rails separated so that if the customer wanted we could add a second fuel tank, pump and feed/return line and then the second set of injectors could be fed with race fuel. This would allow you to run low boost/standard octane on the primary injectors and then run high boost/race gas with the secondary injectors.
