Hey guys looking at my boost gauge after remove my BOV I've noticed that my vacum on idle sits around the 20-25 mark however when the bov was fitted it sat at around 15-20.. Is this normal and whats the cause of it??

When I had my shitty BOV fitted, the vacuum was about 14 - 16. It also had cut at 9psi.

The damn BOV was leaking bad. Too much flow, cause by the leaking BOV. Without it, it sits at 19/20
