With that said, does that mean the compressor will constantly be spun up if I did not have a BOV? So I would always be at the PSI that the system is set up as (unless at idle)?

Furthermore, understanding that the waste gate regulates boost (PSI) level, why do I get a fudder noise when I let off on the gas at a high RPM with no BOV installed? I'm guessing that is because the waste gate is dumping the extra gasses not needed to produce the boost. Hence, would it still dump with a BOV installed?
