it's not adding 8x the fuel into the engine or it run pig rich.. same fuel amount if it comes out one injector or 4(bank) 8 (batch) or the intake floor would be a pond mighty fast..
when you run batch your injectors together fire at once releasing pressure from the shared fuel rail, firing injectors in a staged sequential fashion helps to normalize the pressure pulse. The difference is so minute though I can't see it making any difference in pump requirement.
