Do you mean with the key turned on without starting the engine? If so, that is normal. You are seeing 1 bar which is atmosphere.....

So, with the car off, you are seeing '1' on the stock gauge?

Just for something interesting, with my car off, I show 1+psi boost.

My gauge reads ~15Hg when cold, then reads ~19-20Hg when warm. Thing is, i know i have a vacuum leak from the manifold (3 really). Stock car, on boost i get ~8psi WOT. When i reach 1bar on teh factory gauge, the autometer gauge reads ~8-9Hg.........this is a brand new gauge and im guessing i have some leaks at the connections for that gauge (it was a quick install to check vacuum at idle).
