OK, here's an update from my observations this afternoon:

The angle of the wastegate in the relaxed condition is similar to the one shown in the picture. Actually, the wastegate arm is angled slightly more toward the outlet clamp. (Longer adjustment position on the rod).

As for the operation of the vacuum wastegate, prior to starting, the actuator is relaxed and the wastegate is open. After starting, the wastegate closes and remains closed unless the ECU senses an overboost condition at which time, it vents the vacuum on the control circuit and allows the wastegate to open.

Exhaust pressure also aids in opening the wastegate rather than closing it tighter.

Hope this rambling explanation helps.
