Boost questions?

[The_Great_Tonge]

Today i was thinking what else i need for a boost project and how much it would cost. i was thinking about a set of 340cc injectors, rrfpr, and s-afc. on the other hand i think i heard on this board if i got a profect e-01 it would replace the s-afc and rrfpf if i got the right type of injectors, low impedence i think. also the profec servs as a boost controller too. anyone have any thoughs on the subject?
