Bully,
From what I've been told, the stock wastegate is too small to get rid of
very much of the boost.  Allot of time the engine builder mills out the
wastegate opening to make it large enough.

That's probably why you're seeing boost still, though I didn't see where you
said how high you MAP was.

Today I decided to fire up the engine again and see how far I can go
on the static rpm. As you may remember I totally removed the
wastegate from my stock turbo. This time I was able to rich 4000+ RPM
and 50" MP. Further advancement of the throttle did reduce the RPM
slightly? Looks like the prop was too much for the engine? I was
surprised to see such a high MP with two rather big holes below the
turbine wide open.
Any comments?
Buly
