IIRC the stock turbo can run 19psi, anything over that and you will be killing your turbo.

If you get an AGP WGA you can run more boost. Anything over 17psi and you might start getting a CEL. :cool:

16psi is peak effeciency. You can run 18psi, but that's as high as I would go. Anything above that and you're just making heat, not power.

what about with a huge FMIC ? is it possible to run more boost ?

A FMIC will help some, but it won't change the compressor map of the turbo. fact of the matter is no matter what supporting mods you have, the turbo cannot flow more CFM past 18 psi. Go past that, you start making excessive heat, as well as overspeeding the turbo.
Hence why Stage 3R comes with an upgraded turbo/manifold.
Also, the reasoning for upgrading the WGA(AGP or whatever) is to make the turbo hold more boost to redline, not neccesarily to increase boost. If you can hold 16 to redline or even to 5200-5500 rpm, and you'll have one quick SRT-4.
