vacuum should be around 24" as the engine slows down from peak RPM of the WOT snap
WOT = Wide Open Throttle
It is at 22" @ 2k rpm hot.

The WOT snap produced variable results, a quick snap only got it to 22". A rev got it to 24" and a good rev got it even higher. This engine isn't real responsive though, it revs up real slow.

I still have to check the fuel trims.
