Not sure buddy........0.9bar maybe,but I'm guessing. Someone will be along with an accurate figure.......

13psi is considered to be safe on a standard ECU

had mine up to spikes of 1.4bar with no remap using r-spec mbc and somehow never hit the fuel cut but iv now got it running at a steady 1 bar to be safe now

Top man
Living the volvo dream!!
I have never been able to get any of my T5's to run more than 12psi with an MBC without hitting the overboost cutoff protection at SOME stage.
I currently have one fitted and yes, I can wind it up so it spikes at 16 PSI, the problem is it doesn't hold boost there. I assume the ECU pulls the timing or something because it will spike 16psi and tail off to 12psi and the car will feel as though it is holding back.... also when the MBC is wound out that far it WILL hit overboost on cold mornings or 3/4 throttle if you don't mash the throttle fast enough to make the autobox kickdown.
I have found setting it at 12psi gives a significant gain over stock and the car will hold 12psi without tailing off or hitting overboost........ and for some strange reason it actually feels faster in the mid to top range than setting it at 15 or 16psi.
The way it brings the boost in is so much more aggressive that pulling away from a standing start is much faster, but probably the mid to top end doesn't improve in the same way as you would get with a remap.
ps. I know overboost isn't the correct term but everyone knows what I mean.

Well the Rspec MBC is fitted! WOWEE...... best £29 ive spent in ages
Was going to do a full fitting update, but only had 30mins after work to fit it! So replaced the pipe from the actuator to the valve, fitted the pipe from the turbo housing to the other side of the valve, cable tied the whole thing in place and bob's ur uncle etc etc etc.... I am going to re-fit it properly when i get some time, making it into a dashboard/centre console mounted valve! so i can adjust it without having to stop and open the bonnet! I will post up full pics etc etc etc when i get to do it! But i must say it makes a HUGE difference to the performance, now peak boost at 1.3 - 1.4 bar and holding constant at 1bar!!!! God knows what it will be like in the wet because it breaks the wheels away very very easily now in the dry!!!!!!!!
