Quick noobie question as i just put my gauge ( Auto Meter / 2 1/16 30 PSI Boost Mechanical Vacuum Gauge) on. Completely stock set up with no other mods done yet.

what is normal vacuum that most of you all have, as i am have 20 in/Hg at start up and between 15-20 in/Hg during normal driving.
Also for Boost, 1-2 gears i got about 10 PSI, and 3rd+ gears i was running about 14 / 14.5 .

Is that normal for what most of you have?


TY,
