On the stock TMIC, you the hit practical limit at about 12 PSI in the summer.
If you go higher, the intake air temp rise will limit power.
In the cold winter air - maybe 14.
I envy your turbo.

i dont see the need for beveling your rotors. And 3mm apex seals aernt necessarily needed. They hold up to detonation better. So if you have a good tune you wont really need them. Unless your running mega boost.

as mentioned the biggest factors will be tuning and your intercooler....
I have seen a GT35 on a streetported motor ALL STOCK INTERNALS (aside from the minor porting) with fuel tuned to run 18psi with a front mount.....
he hit just over 400whp on the dyno
beveling the rotors and that is not required to run more boost.....the only thing that will help (and at a certain point is required) is porting......
I would recommend a moderate street port for that setup, plus it never hurts to begin with.....as far as apex seals, 2mm unless youre saving trashed rotors.....
