GTM Stage 1.5 Diverter valve noise

I was also looking into swapping out the turbosmart bpv for a tial bov or bpv. Does anyone know if you need different flanges when performing this swap?

Yes on a flange change. All the different manufacturers have a flange for their particular products. I had a 2nd intake pipe that comes out of the supercharger fabricated and have had flanges welded on for the different valves.
I have tried Turbosmart, Syanapse ( 2 types, the diverter and their newest blowoff which use the same flange) and Tial.

Which Tial did you try and what psi spring?

I think it was the qr50 w/ the supercharger spring.
This was before I did the stage 1.5 kit, so I had it recirculating in the stage 1 setup.
My new setup is vent to atmosphere. I have been looking at the Tial QRJ since reading your post.
I don't have a lot of confidence in my Syanpase diverter valve as it has stuck on me .. Again before the Stage 1.5...
I'm having the new stage 1.5 setup tuned the week of Jan. 23rd.
