Nope, only the S4's with the trip computers have the boost gauge
readouts. Our '93 S4 does not show boost either. I DO have some
instructions on how to add a boost gauge to the car. I asked the
same question shortly after we got our S4, and another Q lister
told me how. Anyway, to the person the originally asked the
question, please email me directly and I'll send you the info.
