When it goes of, there is a pshh sound followed by whinny pshh. I tried to adjust the bov by unscrewing the bolt and turning the threaded bolt with allen but it doesn't do anything. Can anyone help? I thought maybe its the way I hooked it up which was a hose to throttle body and another hose to actuator where the smaller nipple of bov is going to actuator and larger nipple to throttlebody... is that correct? thanks a lot.

 

try the forced induction forum maybe?
