extra injectors or FMU

Eventually im just going to run bigger injectors and a hondata... but in the meen time would exrta injectors and the comp that goes with them be at least better than an FMU... and if im going to run 5-6psi(untill i get the hondata and complete fuel sytem) could i actually just run an FMU at such low PSI with out much problem.. or is the extra injecotrs idea better?
