Did you try using a 3 psi spring instead of the 1.5 psi that comes with it?

I've tried every spring tial offers. I even went the extra step of shaving the lightest spring that they offer to make it even lighter. The noise is still there.

I'm going to say this as respectfully as possible, but surely you expected some additional noise/new sounds when doing such a modification? Especially with a centrifugal supercharger which are notoriously noisy.

A chirping noise never happened with Aaron's previous A2A kit. This one does. Its not a healthy noise because its coming from air being forced out of the supercharger inlet.

I have his first A2A version with the Tial BOV and whatever spring it came with and I can assure you it makes the fluttering noise at 0 on my boost gauge while cruising along the road.
At first I though it was an idler pulley noise, but now I know it's normal for this BOV setup it doesn't bother me.

This sound is not harming anything. It is from the BOV oscillating and the sound is reverbing into the pipe and out of the supercharger inlet. The reason it is so audible is because my Gen 1 kits all came with the KN filter and it muffled this sound where as the ACE kit comes with the velocity stack and pre filter which does not do as good of a job at dampening these sound waves.

It might have something to do with the harmonics of the pipe layout and it is being directed into the inlet differently.

The physics behind this are no different. The same BOV is seeing the same vacuum as the Gen 1 kit. Its always there, just more audible now.

When I tested the Precision turbo 50mm it was MUCH quiter than the Tial QRJ so I am surprised to hear that it is still that audible. In fact, Tony, the owner of the RnD Z, switched back to the QRJ from that PT because he thought the PT was too quiet and wanted to hear more BOV noises.

I also just picked up the new Turbosmart 50mm stealth and am putting that on today to see how this reacts to try to find a solution to anyone who doesn't prefer the noise.

Any updates on how the Turbosmart 50mm stealth reacted?

It is a little less tame than the QRJ. But the PT50 is still quieter.
