MC Wastegate Springs Ordered

... I believe I posted something to the list a long time ago which was an
evaluation of the "Charlie" spring against the stock MC and WX wastegate
springs.  Clearly the spring was a lot beefier than the stock MC spring
(remember though that the MC actually counts on added boost to effectively
stiffen the spring) ...  but there really wasn't that much difference
between the stock urq (WX) spring and the "Charlie" spring.  Perhaps my post
can be found via the archives.  Given the fact that the WX engines have
adjustable spring perches as well, it isn't really clear to me that there's
much need to change springs on the urqs.  Since there is no WGFV on the WX,
I found Paul Timmerman's "Schrappnell Knobben" technique worked just fine to
bump up the boost on my ury ...

One other thing that anyone contemplating messing with the WG should
consider is replacing the WG diaphragm as well ...
