I just installed my SSQV today, and I noticed that the valve performs very well, but after blowing off, maybe 1 to 2 seconds after it blows off I hear surging (I only hear it free reving with the hood up and you make the BOV blow off). So unlike what you would expect, it responds instantly and after the response and a big "blow off" the valve closes and surge occurs after this.
I am running the new style SSQV without any insert in the valve, running off the stock vac line.
Any idea what causes this?
