Use half a hole of preload on a -31 actuator.

port -r = to the airbox is the bleed out,
Increasing bleed off in port-r by removing jet will increase your held

Port- c = from compressor
decrease the bleed size to increase the boost peak spike.

I'm not sure what would happen with taking teh jet out of the w port ,

On mine the w port is jetless, and i have a 2mm jet in the c port and r port is jetless.

but its best to do all this whilst monitoring, fuel pressure, co, afr etc. ie professional.
