I wasn't trying to be rude. When u swap pulleys you are changing belt size as well, this determines how fast the engine is spinning the SC, how can a you regulate that without changing pulleys and belts? Again not trying to be a smart***. I really don't know how to.

Develop a valve that vents when a certin boost is hit. Install it before the maf sensors

Not a bad idea, twin wastegates for a supercharger.

Thats what I was thinking because then you can always run the smaller pulley and just control the boost. No more switching pulleys and belts with a retune and being unable to regulate boost other then gas peddle

what you are looking for exists, it's basically just a bleeder valve so you limit peak boost:
