What should my vacume ( InHG) be reading?
At the moment my autometer boost gauge reads between 20-19 Inhg in idle, is that good? what is normal?

That's DAMN good. That's right where a very healthy engine should be at.

Depends on your portinng, and your tune... but yes that's healthy, especially if the boost gauge doesn't waver or flutter, as the Apex seals go by...
