Boost on a Scirocco 2008 CAWB

[Z900]

I wonder if this is normal the actual boost is 0.25-0.3bar behind the requested, run was made starting in 3rd gear and after that also changing to the 4th.

Check your DV valve also check pcv by putting your finger on the side of the round plastic small hole see if air is escaping

OK, but my most important question is (was) is this normal, or is there something wrong ?
