Question FI Duratec fuel requirements

I've asked around, used some calculators, but I can't get a straight answer.
I currently have 55# injectors, stock returnless fuel system and it works perfectly at 220whp (approximate).

At what point should a BAP be added? When should I make the jump to 80# injectors? How about ripping that out for a return style system?
The (max) goal of my next build is 25psi on a D20 with a GT2871R. That should be right around 400whp judging by dynos I have seen.
I've been told the 55# injectors and a BAP will be sufficient for 400whp. I've also seen where CFM is trying to sell a 300whp kit that includes 60# injectors and a BAP. Seems overkill if the previous statement is accurate.

Pardon my rambles. Lots on my mind planning the build.
