I'm a little confused (easily done) from the above linked article. The article says to maintain the highest vacuum under all conditions, but the 'motor minder' gauge shows 'GOOD' to be somewhere in the middle (not the highest value on the gauge):



I just reconfigured my scangauge to monitor manifold absolute pressure. What value (in PSI) should I have use as the bogey on my scangauge?

*edited to add I have yet to drive it since reconfiguring just a few moments ago - just curious if anyone else is tracking MAP with their scangauge, and what #'s they're seeing.
