depends what rev range you are in mostly, but you will never see full boost at the moment you put your foot through the floor because a turbo works on exhaust gases and needs a short time to spool. At around 4k upwards if you put your foot down you should have pretty instantaneous boost.

yeah i get that part - what i'm trying to find out though is - does everyone else with a standard s3 boost at around 7psi straight away and then gradually increase as the revs go up.
in othewords, what revs do you have to be at before you get the full 21psi?
Expect peak boost at around 4000 RPM.
what shoud it boost too then? 17-18psi?

Eeek!
Stock? Should be like 0.8 bar on a 210 S3, a little more on a 225. That's like 11-12 PSI.
It sounds to me like, if you are getting boost rising all the way through the revs, that something is wrong. What you have there is basically boost creep.
I'd check that your actuator pipe isn't split for starters, that there isn't a split in any of the N75 hosing. Failing that, I would start looking at the N75 valve and the actuator.
I'm shocked that it hasn't come up with a fault code for max charge pressure exceeded.
It's standard yes?

Eeek!
ok sorry, just to clarify, it's 0.7-0.8 BAR and not 7psi.
there seems to be 2 issue's then. 1st one is the max charge pressure exceeded. i posted about this the other day and have since bought 1animal1's n75, fitted it today. I can't scan it as i don't have vagcom.
ther problem i replaced this for is there is a bit of hesitation/boost cut at low speeds that i thought this might have cured.
as for the 2nd issue - the boost guage shows as the revs go up the boost can increase to around 1.3BAR, which is about 18-19psi? this is obviously noyt right
i frickin hate cars
