What vacuum reading do you get with....

....your Profec B Spec II

 

On idle I get about -80 to -85 and when driving, decellerating in gear with no throttle I get -99.

I presume that is in PSI as I have set the Profec to PSI, does this sound about right ?

    I've just done a search on Google for a pressure converter and found one.

    On my after market boost gauge I'm getting -20, this is measured in Inches of

    Mercury and converted that to PSI and got the result 9.283 PSI so the Profec

    and after market boost gauge are very close to each other and I've answered

    my on question LOL :nelson:
