Would it be helpful at all to adjust the timing if your not running stock boost. Stock t25 but with like 15psi? I've heard of people adjusting the timing with a bigger turbo, but what about with raised boost?

No, especially if you dont have dyno. Stock timing is best, sometimes people retard the timing to try to avoid detonation at higher boost levels, but there are always trade-offs...EGT's.... At that boost you just want to make sure you ECU and fuel system are setup for the additional boost.
