Should be between the compressor nipple and t piece if it's there.

WGSP - waste gate spring pressure. A smaller restrictor pill will raise the boost levels, a bigger pill will lower boost levels and no pill at all will run the lowest possible boost (WGSP).

Pic a part? Or STiNGR is wrecking a BH in Chch, SAS would have plenty lying around too. But as above, you'll only be at 7psi max if the pills not in there.

So looking at that diagram, if one has a MBC installed, theoretically hose 10 does nothing?

Or does it still supply pressure or vacuum to something in the BBOD?

There are 2 separate hose #10's. One is the bleed/recirc from the primary boost solenoid. The other is the bleed/recirc from the ECV duty solenoid in the BBOD.
