peak of 1.2 bar which is 17 psi. So it normally sits at 1.2 - 1.3 bar to get that much power, with the hi flow turbos they are all not the same, so Unigroup have told me that i have got one which is pulling more punch since they have tuned it safely and reduced the power just in case, but it could easily go to 270rkw they say.
