Default External Wastegate help!

Hi, looking for a bit of advice please, im having to run an external gate due to my turbo having no internal gate. The actuator on my gate has two control air ports, am i right in thinking i can run it conventionally with one port (the one closest to the manifold) and use a bleed valve to adjust the boost limit, or pre load the spring more. And i suppose the other question would be if i was going to use the top port to balance the pressure, how do i go about its actuation? is it purley electronic, or is there a mechanical way of controlling it?
I also plan on running a screamer set up, just how load are they? im thinking it can also be silenced if its too load? Thanks in advance, chaffe.
