Stock fuel pump

I've been trying to figure this out. I know the stock fuel system is good for ~16 psi or at least thats what I've heard. When I get my car done I'll have 550cc injectors and all the mods in my sig plus hopefully a 3" downpipe(no cat) and possibly a maft. Basically I was wondering how much boost the stock pump can handle safely before it causes it to lean out? Eventually once I get more money I'll be getting a 255 with an aeromotive afpr so it wont be an issue then, just wondering for now

I wouldn't go past 13-14 just to be safe. why risk it?

good point
