Finding a 5kcstq

[Steve Ensch]

I have been looking for a 86-90 5000-200 turbo Quattro.  I have noticed the
cars are very solid, except for a few with tappy valves, steering rack
leaks, and minor interior problems.  But I have noticed that several don't
show the correct spec for boost.  1.3-1.4 is the correct peak range.  I
looked at a couple of both stock and modified.  The modified cars had a cold
air intake or the a k&n air filter, combined with a modified waste gate.
These modified cars did not pull to the 1.3-1.4 range.  Could improved
breathing lower the pressure or is this a sign of improper mods, or
impending doom?
