[s-cars] Boost leak - update, what am I missing here?

[QSHIPQ at aol.com]

No, on the urs4 it works the opposite.  With no WG intervention, the  boost 
is WG spring pressure only. The valve limits the amount of  boost pressure the 
WG sees.  When it goes bad, it's either slow, or  defaults to open, which 
means that the maximum boost is the WG spring pressure  only.
 For unlimited boost (ala 5kt cars of the 80's) you put the WGFV and  
pressure to the top of the WG.

On test  #4, if you removed the input line to the wastegate you should have
seen  basically unlimited boost if you kept your foot in it, if I am  thinking
about it right.  If you did not see tons of boost with that  hose
disconnected I think you may have a turbo problem or a massive  leak.  Am I
remembering this plumbing right?  I have a tendency  to get mixed up between
the 10 valves and the 20 valves here as they  reversed the plumbing to the
WG.
