Where is the boost pressure source in the a2a supercharger? I'd like to reconnect the boost gauge.

I connected the boost gauge with a T fitting to a 1/4" vacuum hose connected between the barb and the tial bov in front of the stillen manifold.

The bov vacuum hose was changed to 1/4" and the flutter noise was better than before.

But Tial reaction speed seems to be slow.
The bov is open well when idle. Compressed air also comes out well. But I think the closing speed is kind of slow. A little flutter.

Is it better to connect the tial bov vacuum hose directly to the manifold?

I want to press the boost gauge somewhere else. Where can I do it? Do I need to connect the boost gauge to the barb between the two throttle bodies? Alternatively, can the T fitting be connected to the brake booster line?
