Bov adjustment question

[mikevar94]

Just purchased the gfb respons bov for my 2g. Awesome bov so far. Sounds great and actually seemed to improve throttle response slightly. My question is where should the spring perload be at? I know there are many write ups on this but I wanted to make sure it's not different with this bov since it'll vta and recirc. Current set up with it is about 60% recirc and 40% atmos. Also I noticed it does not really sound when just revving in neutral. Well it does but very little and only heard under the hood.

We'll in idle when revving up your not really boosting heavily enough to hear it like you would while driving. And the more recirc % the less boost lag and it should run smoother. Less stumbling
