Hallman Pro MBC make noise in boost.

[JMiller]

I have this issue with my hallman pro where when i get to 5psi the boost controller makes a whirling noise. I did a BLT and it seems like at 5psi the spring and ball inside the boost controller starts to spin around making this noise that can be heard over the engine and the radio(loud). I only have it set at 12-13psi which is like 2 turns past nothing, so just wondering if this is happening because i dont have it turned to a significant amount or if this is just a regular thing with hallman boost controllers.(or my unit is faulty) Thanks for any help.
