That's a great amount of power for such low boost pressures. Your car, if tuned well will run very safe and you have a ton of headroom to make a lot more power with the expected fuel upgrades if you wanted to. But, Your reliability will suffer going higher. My motor blew up on me with the setup below. I did have a vf39, close to maxed out and past its efficient area running at 19.5psi which is 1.34 bars.
To give you an example, I also have an 08 hatch ( Hell yeah another narrowbody!!) I have a fully built short block, full water to air intercooler, turbo back exhaust, EWG, boost controller, tgv delete and I'm pushing the vf39 into flamethrower mode at peak target boost being 22psi and it's currently tuned mild to run this setup safely and it will on this built motor and the water to air setup being able to cool the charge, but that's this turbo's limit.
I will go to something like an 18g with ball bearings and conservative tune to lower psi for similar boost figures as you and similar power, maybe a bit more until I'm creeping up on my fuel system limits.
