2G Why is this ran like so?

Why would the previous owner have run a line from the intake manifold/throttle body area, straight to the waste gate bypassing the stock boost controller?

To run straight wastegate pressure, but it should be on the charge pipe, pre-throttle body. Sounds like incorrect install to me.

The only real issue I see with using manifold pressure is the wastegate actuator will see vacuum as well as pressure.
It will achieve the same basic result really, set pressure opening the wastegate from manifold pressure rather than turbo compressor housing or charge pipe.
What you see on your boost gauge is the same signal the WG actuator will see.

Wastegate chatter when going on/off throttle.

Are you sure the hose from the intake is to the waste gate? By chance could you mean BOV?
