My Greddy Type RS is whistling. How to fix it? Hard or Soft?

[kmoore]

Guys I know, i know another bov adjusting question. I'm sorry but i have searched about this specific topic and all i get is the type-s bov. So here's my situation, i got my type-rs about a couple weeks ago and i have still have been trying to get it perfect. When i rev it in neutral at about 3000-3500 rpm i hear this long whistling noise. Does this mean i need to adjust it softer or harder? Thanks

I just installed my RS. Recirculated. Sounds sick... Had to take out the small spring because of turkey issues. But now its awesome holds boost without problems. Much more improvement from stock bov!!!! I love it!!!

i blew the diaphragm out of my old rs, it kinda fluttered after that
