got boost (slight return)?

FWIW, I just installed a Faze brand boost gage on the driver's side A piller - or whatever Audi calls it - in my '91 200 20V TQ.  Picked it up at Advance Auto.  It is a beautiful gage, with aqua backlighting that matches the Lago Blue exterior of my car.  I hooked the gage's power transformer into the cigarette lighter light supply wire so that the instrument panel dimmer control controls the gage with the rest of the instrument lights.  
  The other nice thing about the Faze model gage is that you can (and I did) buy a cowling for it that you can trim to exactly fit the contour of the A pillar.  It is a beautiful install that looks as close to OEM as you can get.  (I toyed with the idea of putting it right in the instrument cluster in place of the digital readout, but figured that that could result in a host of other instrumentation problems so didn't do it.)  I can get a pic if anyone is interested - email offline - and advise on fittings needed to tap into the IM hose.  It looks a heck of a lot more "finished" than the pic I have seen of a boost gage on the sjm or cjmiller site - can't recall which.  Total cost: $100.  I now know I am getting 21 psi of boost at full throttle, though am surprised at the "few psi plus/minus" needle bouncing that occurs as soon as 20 psi is reached.  Mike in KC, MO

  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!
