Whats most boost I can run?

Hi,

so my car is back. The previous motor had put a rod through the block.

It has a HASS stage 2 bolt on kit and then had stock internals

I have since replaced it with a second hand 1zz which we completely rebuilt. I'm wondering what is the max boost i can run. Here are the specs:
- Wiseco 8.8 pistons
- MWR valves
- MWR Rods
- Cometic head gasket
- ARP bolts on the fly and head
- Block has been rebored slightly
- Hass Stage II bolt on turbo kit (modified and improved)
- Turbo Garrett GT2860RS Disco Potato
- Bottom Mount intercooler
- Aquamist 1S water/meth injection system
- Full 3 inch exhaust with 1 cat and 1 bullet muffler (2 outlets machined from billet stainless steel)
- HKS SSQV blow off valve (genuine, not Chinese reproduction)
- Siemens Deka 630cc injectors
- TRD helical limited slip diff
- C-One solid engine mounts
- ARC oil catch tank
- ATP 3 inch MAF tube
- Ogura Pro Carbon Clutch (Multi plate with matching flywheel and release bearing)

I'm currently boosting at 1.1bar max (about 16psi) and it made 339BHP at the flywheel
Had it tuned on Saturday. No knock or detonation even at this boost.

That number is already more than I would have expected with a GT28RS and intercooler.  IIRC 16psi is right on the limit of the sweet spot for a GT28, any more boost and you'll be generating more heat than you can cope with (even with a chargecooler). Of course you could up the ante with the water injection but I'd have thought you'd be running that as a safety net.
No mention of valve springs or cams?  I would suggest that if you had the uprated springs you could rev higher and grab a few more bhp there and maybe a bit more torque if you had the cams, but otherwise I'd say you should be very happy with that result.

Thanks.

I am happy with the figures. Just wanted to know if its safe as is and where i stand compared to max boost i could run
