I would say you're flirting with disaster running a stock fuel pump and injectors with those mods and a 150 shot.

Walbro255. Since your an 05 you have a returnless fuel system so you can't add an inline pump so you'll have to do an intank. If you can do one or the other prolly should go for some injectors

Your best bet is to get some 8.1 marine injectors. I think they're around 44# and usually around $250. They'll be good for you even if you decide to add a little boost.
