the cost and time to install a mechanical boost gauge (Autometer makes a 
very nice ones) is well worth it, IMO.  Nice to know what kind of boost and 
vaccum the engine really is seeing.

I live with mine slightly less happily. I too have a chipset (from
Hoppen) with the same non-calibrated factory boost guage. The
difference in my case is that for the first eight years I had 1.7-1.8
showing all the time- and I suspect that there is a true loss, key word
being "suspect", since my seat-of-the-pants technology may be
imperfect. But I'd be less suspicious if my subjective impression
didn't jive with the admittedly imperfect factory boost guage. But the
car runs quite well for which I'm glad, and I don't often use full
boost. I would be happier if it felt stronger when I did put the turbo
to task, but it isn't a big worry. I'm more concerned about brakes,
climate control, seat heaters, and other daily use stuff. All of which

91 w/chip and RS2 manifold. feeling less spunky.
Still wtb  ur-S4 wheels!
