Factory boost on the US urq w/WX is 10.X PSI over ambient.  The value is temp dependent, you can see the spec chart in the IST M&A, which you can find on Martin's site (which is a link on the urquattro group yahoo page noted in the footer).

If memory serves (and that is a very big IF), the stock spring in the stock cap gave about 8 PSI. If screwed down via the center screw it could go higher.
