Safe boost for a GT30

Not been out in it properly yet but from what my Dad says, it's very lively, goes a lot better and despite being 4x4, needs treating with a bit of respect.
From the brief moment I was in it, it was very smooth and well behaved off boost but came on boost nice and progressively. I've not felt it at full boost for more than a couple of seconds at most.
Apparently something along the lines of full boost by 3.5k and still making 32psi at 8k rpm.

Sorry my mistake, i thought you had it booked in or something.
If it were me, i would ring a tuner who you would be happy to take the car to and ask them. But just because joe bloggs maybe running 6000psi dont mean your engine will as until the tuner actually gets to work on it you wont know.
My t34.63 could in therory run at 36psi , but as my inlet/head work/injectors were flat out/becoming restrictive at 28psi thats all I run. Thats on an msd live map which is faultless to drive.
you see.

Hi Graham,
The GT30 eries of turbo will generally be fine with 2 bar of boost. My first question has to be, why did Reyland / NMS limit that turbo to 18psi on that engine? Also, was it mapped to do the full potential if you DO turn it up, or does it need mapping as well?
I would be seeking the answer to those questions as my first port of call if i were you, just incase there is a hidden gremlin you are not aware of with the new beast.
