and mine reads 0.9 at atmospheric (ignition on, engine not started).
I calibrated it against a hand vacuum pump.  It's out by 4" Hg or about .125
Bar for all pressures below 1 Bar.  It also never shows more than 1.2 under
boost... which translates to 1.3 which is about right.

In short, these displays aren't very accurate, +/- .1Bar error at least!
