Dear Listers,

    I'm sorry if It seems that i am beleaguring this topic, but I had a
hypothesis about my car's reluctance to realize full boost (1.8 bar).

1.0 bar is normal atmospheric pressure, right?

The highest reading my car will show is 1.5 bar.

When the engine is off, the boost gauge reads 0.6 bar, signifigantly less
than Atmospheric pressure, a vacuum.

When the engine is not running, is it reasonable to say that it is not
pulling any vacuum?

if so, then...

Would it make sense then to say that my boost gauge is calibrated  -.4 bar
too low? or is this display of vacuum common on Audi 200q20v's?

Thanks for your patience,
