30psi? Wow. Might Hoppen have put in a 2nd head gasket to reduce
compression? Are all 5 cylinders consistent?

I have a 137k mile '95 S6 which has had RS2 turbo and manifold, Hoppen 30psi
kit, etc. installed for 90k+. It's still running great with no signs of
problems, but a recent compression test revealed 105 psi on all 5 cylinders.
I haven't yet done a leakdown and oil compression test, but do any listers
know what the factory values should be and what they might be with an RS2
exhaust cam?
