I can't see where the bypass could be leaking to the outside - I'd see some
crack or something, right?

Let's assume the bypass might be leaking (internally) - why/how would that
effect the observed boost pressure?

Right - I have a fitting installed in the turbo intake, and directed toward
the impeller.  I did this so the bypass flow would enter already going in
the right direction.

I played with 2 deg. advance and currently have it set for 3 deg. retard.
 The idle was not noticably affected with the radical cam, and I have left
it that way with the stock cam.
