> If that is so then why is the waistgate in its stock position before the throttle body?

Because the wastegate has nothing to do with throttle opening/closing.

Wastegate relies on pressure created by your compressor (if any).

When you’re boosting your wastegate sees the pressure and opens accordingly.

When you lift off throttle, your BOV should purge excess air (thus closing your wastegate)
