That 14 is a big improvement after I did a new canister, vac lines, check valve & plenum rubber.
If I have a leak the only other place I think it could be would be pass side (bank 1) intake gaskets.

I don't know if it's physically possible, or for that matter advisable on the Boxster. But back in the day we would spray some starter fluid around the intake manifold gasket area on the old British sports cars. If the idle speed increased that was a sign of a vaccum leak at the gasket. But cars were much simpler then, maybe this isn't a good idea on a modern car if you can even get to spray in that area.
