Default GTM Stage 1.5 Diverter valve noise

So I did my first drive after installing the Stage 1.5 upgrade...
Originally my BOV plumbed back with the stage 1 kit. Relatively quiet but fluttered under medium acceleration.
Now, it vents to the atmosphere and is loud as hell, almost sounds like my wheezing grandma... for lack of a better description.. lol
I have a turbosmart plumb back and also a synapse diverter valve.
What are you guys running with what spring and how tightened down do you have the spring.
Is it loud also when it blows off?
I'm looking to quiet it down a bit...
