do i need to upgrade fuel pump/injectors?

I have intake, dp, cb, and pfc. I want to do a smic (greddy or asp) and either high flow cat or mp next. my question is do i need to uprade the fuel pump or the injectors if I keep the boost @ 11-12psi. Thanks

Why risk it? I'm putting my motor back in now, and I'm going from intake, dp,catback, to street port +microtech+MP+ASP large SMIC AND a complete fuel kit. The last thing I would chose to go cheap on for this car would be the fuel system.

Get the Bigger injectors now, as one day you'll be tearing it all apart again to upgrade your turbo and you'll already be set.

Pump usually is the first weak link in the fuel system then injectors (if you already have an ECU)
