Default How do you tune a BOV? (APS 50/50)

Does anyone know how to adjust the APS 50/50 Blow Off Valve?

I imagine you need to tweak where it starts to blow off pressure... maybe for both Intake and Atmosphere sections.

I've got what feels like slow boost recovery between shifts on a Stage 4 setup. I'm wondering if the BOV isn't adjusted properly.

Thanks,
Russ
