Default Very low boost, but car seems perky?

I've hooked up a boost gauge, and it seems I'm building around 2-3 PSI around 2500, and it doesn't go any higher when getting on it hard.

I've pressurized the intercooler and everything down the line, and it's dead silent. Barely audible hissing around injectors at 20 PSI.

When running in 3rd with almost WOT it goes from 3000 rpm to 6000 rpm (30mph to 60mph) in 6 seconds. Does this sound like low boost?

Any ideas where to start on this 99.5? I have a VAG.

I thought 1800 millabars was the norm? I could be way off.
