Default How accurate is the factory boost gauge?

The reason I ask is because it keeps stopping at 0.09 or 0.087 Megapascal, since the factory boost is set to 14.5 PSI, should it go up to 0.1 MPa? My car feels very strong, but I'm curious. Thanks.

Both of mine stop at just right of .9, like maybe .95 if I had to take a guess..

Don't know how accurate it is.

The stock boost guage is mechanical vs. electric... So it is not THAT accurate. It's better than nothing though
