Mk2 cupra standard boost

[Sandypark8]

Anyone know what the standard boost should be sitting when idle and holding at when on boost ?

boost gauge in my car sits at the bottom at -1 bar and hold boost at roughly 0.7-0.8 bar?

Full boost: 1 bar@2200 rpm
Constant pressure:0.85bar
Pressure at rev limit:0.7bar

I'm guessing the -1 is cause it's under vacuum when not boosting.

Not that this helps you in anyway but....my 1.9 TDI boosts to 20 psi at max boost......but then.......it's a GT 17 turbo so believe it should only go up to 17 psi
