Default How much HP will stock injectors make?

I have a 2000 SS and with a cam and bolt-ons and I'm being told I need to upgrade my injectors. Is it necessary and which ones should I go with. My only future plans are ported heads and dual exhaust.

I've been told stock injectors are good for over 400 HP.

Did you use those injectors with nitrous, or have you upgraded sense then? What size shot are you using and wet or dry? Thanks! Your setup is very similar to what I ultimately want out of my engine.
