I was adjusting my new BOV today, and left the bolt far enough out for me to vent at about 3500 rpm. I went to a local shop that a friend of mine runs and he said that it was set too light and i really shouldn't vent in nuetral(lack of boost build up). so im torn it runs ok both ways and there is no real loss of boost when its really light, but i think im losing spool time. I'm lost in too much info.

P.S.
When its set really tight i hear wastegate flutter and the BOV doesn't vent as noticably

 

i'm assuming you have the HKS ssqv??

the only thing i can think of happening is:

1)when you set the screw too light = boost leak at high/full boost.

2)screw too tight = bov doesnt open or doesnt vent as much boost when the throttle body closes, causing turbo spool lag and or damage to the turbo.

 

should have left it as it came

 

i agree. Right out of the box, it should have worked fine the way it did.
