NO is vented to atmosphere - move the nipple from NO to NC.

Run a line from your boost reference at the compressor outlet (or boost pipe that goes to the throttle body) to the bottom nipple of the external wastegate. Put a "T" in this line, and run the hose from the T to the NC nipple on the AVC-R solenoid.

Run a line from the top nipple of the wastegate to the COM nipple on the AVC-R solenoid.

Is it plumbed in like the above?
