2005 twin turbo z in need of help

[Need2Speed]

Hey guys, I just put the greddy twin turbo system in my stock Z. I purchased a defi boost gauge that reads into bars instead of psi, I was wondering if anyone would be able to translate psi into bars for me. I was also wondering there were any good tuning shops on the East coast. I am in NYC. If anyone could be of help I would be greatfull
thanks

My chemistry might fail me, but i think gravity = 14.7 psi = 114.3 bar?

I think 1 bar = 14.7 psi. Or barametric pressure at sea level.

[got celica?]

bar is just the metric measurement of pressure (which you're used to thinking of in psi)
