factory psi?
WOT= around 14.5 psi according to my autometer boost gauge, anything less than WOT=between 5-10 PSI. that darn wastegate and or factory boost controller don't like boost =( unless flooring it which equals =)

factory PSI is officially 14.2 psi, or 98kpa (.98hkpa). wastegate pressure is around half that (between 7-9 psi depending on the wastegate spring).
on my blitz dtt with boost guage, I was getting about .98 - 1.00 hkpa before my EBC was installed.

Peak pressure will be different depending on what gear you are in. Also, your boost gauge may not tell you accurately how many PSI you are running. For example if you are not at sea level (in the mountains, etc) your boost gauge will read high. It may say you are at 15-16PSI when you are really at 12-13. Boost gauges give you relative PSI not absolute PSI.
i have the blitz dtt too, and i always peaked at .98hkpa. when i had the 3/16 mod, it spiked to 1.03 or so, but when i added the silencer mod along with the 3/16 it spiked to 1.1hkpa. now im back to stock, too much spiking
