    Ok so hg is just another measure of pressure invented by the Americans ....

    The minus of most gauges is in hg and it should sit at -20 on warmed up idle.

    You must have an all psi gauge including vacuum. Anyway I know mine is spot on because it runs perfect.

    That’s what I’m inclined to think, mine runs great too but I can still hear hissing from the brake servo

    Default Vacuum at idle

    - 23 hg on cold idle, rises to around -20 when warmed up on mine
