I read this from Unwired Tools website and I conclude that 911st analysis is the most logical to what is happening to my car.

This is for the UTCIS-V but probably applicable to UTCIS-PT
pages 8-11

The correct manifold pressure for the digiWUR should be 0.4-0.5 bar at idle and mine is 0.9 bar at idle. It says that if it is 0.6 and greater, it could have a weak vacuum or could be what they call "performance camshafts."

When I put a small load on the engine, the manifold pressure should go up from 0.4 to 0.6 or0.7. With mine, it is the other way around from 0.9 down to 0.6 or 0.7 then goes back again to 0.9 on idle. This is probably the reason why I am always on the rich side eventhough my control pressure is on 3.8 already.

911st, basing on the picture I posted, do you think it is hooked up correctly? Or is there a better vaccum line for the digiWUR to be hooked up?
