If you car is making 195rwkw it is not running 10psi.
I have my car tuned on .75 of a bar and that is appoximately 10psi my car makes 184 rwkw and has no prolems at all.
i have a wlbro fuel pump, AVCR, turbo back exhaust, splitfire coil packs, platinum plugs and FMIC.
I found that when i had the AVCR installed my car was all ove the place when boosting, but have since taken it in and had i tuned properly and now have a great power curve and a reliable car. Note that they could not put anymore boost in as the factory computer was dumping timing and fuel with anymore boost.
