I have the Greddy Type S blow off valve, i'm not venting to the atmosphere it goes back into the intake, and i was wondering if i need to adjust the top screw or just leave it the way it came.

unless you have boost creep then you shouldn't have to worry too much about it. Just tune it. Tighter makes for alil quicker spoolup. and if it's too loose it won't hold boost. (depending on your setting)

I fear for the future of humanity in general...creep is due to wastegate flow, not which bov you are running.Originally posted by 98GS-TSpyder

you are hurting performancei am venting to the atmosphere.

contraindictory. do you have a boost gauge? What do you consider high? How can it be high if you don't hold boost pressure?also i seem to not hold boost pressure (which seems high) in most gears.
