dude shoudld you own a rx calling it a pos???? But anyway the secondaries arnt gonna open with no load unless you make them mechanical. SO take it out ond get it up to 40 and tromp on it hard. You will know if they dont open buy your face hitting the steering wheel!

im calling it a pos cause listen to it when u dont press the valve if it didnt make that noise then no i probably wouldnt have this problem and no i wouldnt call it a pos, and it does the same thing while im driving, before we pressed the valve it struggles to hit 4k rpm, wont even go to redline, my face wouldnt hit the steering wheel if i have my seat belt on now would it.

It kinda sounds like it is running on one rotor at idle. Are my ears deceiving me?

Yeah sounds like it's either 1 rotor or half ignition. Pull the plugs. How do they look? Are you getting fuel thru both primaries?
