S4 turbo pressure measurement

[Morten Astrup Steen <mosteen@sn.no>]

Hi friends,

I'm starting to get used to my new jewel, the '94 S4 aquired not long
ago. Some details bother me though, the only thing I'll bother you all
with today is this:

My digital turbopressure gauge shows 0.5 at idle. approx. 0.9-1.2 at
normal driving and when really hitting it I've seen 1.7 and I think 1.8
once or twice. Is this correct?

I thought it should be 1.0 at idle (atm. pressure) and only below 1.0
when breaking with the engine downhill (so that underpressure would be
created). Is this my paranoia or is something not right?

Thankful for any relief from you gurus out there :))

Best regards,
