ok. I kinda understand that but I'm still a little confused. So if you want to run 20psi you set the manual boost controller for 20psi? and keep the duty cycle of the gm solenoid as high as it will go to basically just keep it open and let the mbc limit the boost to 20psi? and because the mbc is at 20psi it will let anything below that flow through just fine and use the gm solenoid to regulate boost? So I guess with the way you have it setup the gm solenoid does most of the regulating and its only under wot that the mbc really takes affect? This sounds like an awesome idea, I'm just trying to understand how it all works.
