When are you hitting your 5.2 bar full boost?

I do not know the T4 unless you are talking about the turbine mouth size. Do you know the hot side's A/R?

Nice thing about Turbonetics, you can usally buy a next size smaller turbine housing and just fit it to your existing turbo for I am guessing about $200.

A smaller A/R will get you to earlyer boost but often costs at the upper rpm range.
