Default Clarification on GM solenoid hookup

Hi, could you clarify this for me? Do you mean that you leave the little foam filter on the solenoid, or do you mean that you SEAL UP the port? I really like your setup; I was just about to try something almost identical, but as far as I understand three port solenoids, you need to alternate the turbo outlet pressure and atmospheric pressure to the common (wastegate) port for it to work properly. I was assuming that I would pull off the little filter and route that port back into the stock fitting on the intake for the atmospheric source, as it is filtered and past the MAF. If that port is sealed, I would think that there is no way for the pressure in the wastegate actuator to fall, except through a bleed hole on the MBC

Thanks for your help,
