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. --------------------  |

Its an auto meter I can't imagine its very accurate. Defi is a bit out of my price range.
