Vacuum Leak Question, A bit stumped here Options

[bsamps4]

My car only runs around -19 vacuum when at idle. I have changed from the stock bov to a synchronic bov in hopes that I just had a worn out factory blow off valve, but there is no change in vacuum...my idle improved slightly (but i think this might be due to the synchronic valve in the open position at idle) I have checked and checked and checked for a vacuum leak and have yet to find one. I've replaced several lines, sprayed everything down with starter fluid, re-checked all of my boost clamps etc....Is there something i'm missing here? It seems like I should be able to locate this issue no problem. The car boosts great, but I'm just worried that i've missed something. Are there any common fail points that I should re-check?

Note: both blow off valves are making the same noise. After looking at youtube it would seem that it should just be ONE pssshhh. Mine sounds like psssshpssshhhpssshhh.

youre fine ben, 19-20 is normal, my first swap ran 19 vac. using an auto meter boost gauge. right now, mine on the other hand is reading 15-16 for some strange reason...
