I've fitted a HKS SS BOV to my wrx 95, when I accelerate and chnage up though the gears, I've noticed that the boost takes quite a while before it goes back upo to 15psi after each change.

Is this correct or is there something wrong with the BOV, or do they all do that?

Thanks

 

try turning the screw in at the back half a turn at a time until its boosting properly.

Thanks for that, I'll try it a try.
