Something in the 205-215 range...maybe a little higher or lower..I am not totally sure. Most max stock boost out of a OBS 7.3 I would guess would be something like 22-25 psi. I would do headstuds if you plan on going over 40-45psi, you stock turbo can not efficiently or reliably handle much more than 27-29 psi. First before adding anymore fuel get some gauges, at least a pyro and boost gauge and I would recommend a tranny gauge if ya got an auto.
