This is an old and highly covered issue.
I'll cliff note it for you
12-13 psi == safe. Many have been running this range for years reliably
14 psi = Scimming the range of compressor effeciency. Your turbo will hate you for what little time it has left as this will severely shorten its life expectancy.
15 psi = strap some M80s to the turbine wheel as it will grenade in short time at this rating. Also, this boost range puts the compressor way out of its effeciency range.
