I'm pretty bad at explaining this, but since I'm running a -2psi spring in the tial q, my guess would be when the high cams roll on, the motor is essentially taking a deeper breathe and lowering the pressure at the manifold, so now the blower/charge piping where the BOV is, is at 10psi but the high cams may drop the pressure at the manifold to 8psi and the pressure in the charge pipes being just greater enough to crack open the valve. This is all I can think of for now but it makes sense in my head. It always happens at my vtec point and never before that even though I get up to 9psi then it cracks, then all of a sudden at 7000 you can hear the leak just stop entirely and the boost shoots back up then leaks again, so it seems like the BOV or wastegate opening, but can't be the wastegate since I have it mounted backward so the pressure is holding the valve shut and the boost solenoid isn't activated at this point in tuning. I'm going to post a pic of the bay to show what I mean for my placement. Also mind the piping lol long story, but it stays until my next upgrade.
