Default Boost reference FPR base pressure

What is everyone's suggested base pressure? Right now, I have mine set at the stock pressure, 58 psi.

I'm in the beginning stages of tuning, I'm thinking that I may be screwin myself. Just want to make sure that I'll be alright if I decide to run any decent amount of boost.

Use whatever pressure is required, and your system is capable of handling.
