Boost inHg/psi
What is considered a normal reading at idle for a boost inHg/psi gauge to read?

I am referring to a Aeroforce interceptor scan gauge.

I dont use an aeroforce gauge, but my Prosport typically hangs around -18psi at startup, -22psi at warm idle. Peaks 27psi Tapped at the throttle body spacer.

Prosport gauge.. mine will hang around -16 to -18 mostly. But while driving will see between -25 to +27 pressure fluctuating. It think it will also depend on your tune, tap location, and ecu idle tables. My idle tables are set low so it gets a heavy vacuum reading.

Generally its in vacuum in idle. General good vacuum should be between 17-22 in Hg
