BAR to PSI conversion on gauge

[eclipsegsx1736]

I have a Greddy boost gauge that measures in BAR, any way to take the face out and put in a PSI face so that I can have it in PSI and not have to replace the whole thing? thanks

Save yourself the hassle and spend the money and get the auto meter boost gauge. all my gauges are auto meter and they are accurate, they have never failed me!!!

it doesnt read boost at idle, when i rev it on neutral the max it shows is 7psi and while im driving it and i give it gas and reads about 13psi. Yesterday i put in a mbc and i was just trying to figure out which way to read it.

It should show no boost in neutral. Turbos are load sensitive. With no load on them they should not build boost.
