its up to you mate if you like the little wooosh sound make it half and half if not fully recirc
What ya mean half and half? you cant change the amount of noise vs recirc............... the twisty bit is only the spring stiffness - to hold the pressure all the way until you lift off the throttle. amount of sound is dependant on the level of boost. mines louder now on 20 psi than it was on 10!!!
ps Lee....... shuushhhh! its a rubbish noise you can barely hear!! and even worse in reverse - stupid budgie squeek!
