Just curious how you hooked it up.

Did you run two lines to the Tial wastegate, or just one?

Default I am running the HKS EVC4 with a external WG

Hooked mine up with one at the top and one at the side, plus the one to the compressor housing.

Default Pretty sure the one on top should Y into a line that goes to the turbo housing

for pressure. Which means there should be 3 lines total but only 2 going into the step motor.

Default So, you've got yours like this

But there is no 3rd connection (where it says open or to pre-turbo inlet)

There are definitely only two holes on the step motor. You are right, the side line "y" to the step motor and to the charge pipe.

Default Here's the TiAL diagram, did you add a vent in yours?

Right, but one of them should T into the intake manifold vacuum line.

Default Correct...

Default

looks like you only add a vent if you want the W/G Spring to control the pressure
