750 RPM (keep in mind the tach has no mark for 250 RPM)
I think the vac spec is 17-18 in Hg at idle? Not 100%. Most sit a little better than 18. Convert that into whatever units your gauge uses. |

My idle is at 750 but my stock lamco gauge doesn't even have 17 or 18 hg it goes up to .1 which is only 14.5 mine sits at .07 doesn't make sense ?

600-800rpms after entering closed-loop mode (your car is warmed up), 16-22hg (this is not a negative value, btw)

If you say 15 in Hg vacuum you are saying that the value is a negative value in relation to atmospheric pressure. 15 in Hg vacuum = -15 in Hg below atmospheric pressure or ~ 14 in Hg absolute( atm press = ~14.7 psi = 29.9 in Hg) 15 in Hg = ~ 7psig if you are not talking about vacuum specifically so eventhough the number isn't represented as a negative, it is. |
