I do have a BOV . I was thinking about taking it off and looking at it but not sure how to tell if its malfunctioning.It does seal when i test it an spray it with water.
I did a cranking cyl psi test yesterday and had 190 psi in all cylinders. Normally it has 170. I guess the new head is making more pressure. That explains why it feels faster per pound of boost i guess. I guess the smaller runners made this happen. Ill have to see if that changed the vacuum. Maybe when on and off the throttle the bov is out of sync like you said..
Thanks Paul..
