RUF put a .6BAR spring with DOD and it gives .9BAR with boost dialed all the way in. For everyday street use you are pretty safe with a stock intercooler at .9BAR. My understanding is that much more than .9 and you will want a bigger intercooler.

My experience with upgrading to a B&B Headers/Exhaust with the wastegate is that it will still open at the prescribed presure corresponding to the boost as it did before the free flowing headers and exhaust. You should get there quicker though.
