According to the Garrett compressor map, a pressure ratio of 2.25:1 is achievable at peak mass flow (1.25 bar gauge). Just over 2 bar gauge is achievable at lower mass flow rates.

Standard 56 trim wheel wont quite reach 2 bar maximum boost.

There are many variables to take into account, however ultimately it will be what your setup allows. Whoever is tuning your car should determine this threshold, every car is different and just because you "can" doesn't mean you should.
