Several people have emailed recently asking for a spring.  Would you
believe I'm finally out of them.  I need to get to the place that
wound the first batch and get them to make a few more.  As soon as
that gets done, I'll try to email everybody that's asked, and I'll
post something to the quattro list too.

These springs result in 1.6 to 1.7 bar boost, and can be shimmed
for perhaps another 0.1 beyond that.  At the same time, you have
to bypass the overboost cutoff done by the ECU.  When I send a spring
to someone, it will come with instructions and a discussion about
the effects of bypassing the ECU cutoff.  I recommend you read
Scott Mockery's web page on raising the boost on the 10V MC engines:
