I did a search and couldn't find what I was looking for. If I had a dp, cb, intake, boost controller, pulleys, radiator, and ecu, could i run @ 12 psi or higher on stock fuel pump and stock injectors?

It depends on your ecu. If it has maps rich enough for >12psi, then yes, if it's tuned for 12psi, then no, find that out, but this is why it's a good idea to go programmable, because then you decide what boost you would like to run.
In terms of stock pump/injectors, each car is slightly different, so there's no simple answer, but the Power FC guys can tell you injector duty is a good tool to measure this. (unfortunately, a reprogrammed ECU will not provide you this data, you must have a programmable as well)
Get the hint of my advise? I'd be safe with 12 until you find an answer for what you're ECU was mapped for and find out how hard your injectors are working.

Some people will tell you no, some people will tell you yes..

IMO, the stock intercooler would be more of a concern than the stock injectors. Search for posts by Wade, he has been running some serious boost on stock injectors without any problems.

As for the fuel pump, it should be fine but it's a fairly inexpensive upgrade to do. If you have the money, it's not a bad idea to upgrade it but the stock one will be fine for 12 PSI.
