I'll take a few today.
What's the typical vacuum for this engine at idle with no load?(i.e. in park or neutral) I compared the vacuum on the cobalt gauge to a vacuum gauge from harbor freight and its off by about .5 in. Hg.

What does the vacuum read at first start up?
I wanted to install the boost/vacuum gauge for the extra engine info( i like gauges, hate idiot lights) and also to help troubleshoot another little problem that I can't seem to figure out.
