    I would use the -9psi.. It has to do with the idle vacuum reading.

    And they are right. Stiff springs are good for automotive applications, but for PWC applications you need fast pressure bleed with slower valve closing speed -- this reduces unwanted and harmful pressure waves going back at the SC shaft and clutch system.

    Thanks for your answer, i am going to install the 3psi tomorrow morning then i will test it to see if it works properly.

    Note : the spring that the BOV had (the one that was using the turbo set up) only opened at high boost, at low boost the air will return to the s/c housing
