It has been brought to my attention that IPD uses a different port configuration than what I use on the TCV. Since IPD switched solenoids to match the solenoid used in the Phuzzy Motorsports HD-TCV, I feel it is very important to point out the proper configuration for safety reasons.
For orientation, Port 1 is the right-most port when looking at the valve head-on. Port 2 is the left-most port. Port 3 is the center port.
Port 1 is Normally-closed to Common
Port 2 is Normally-open to Common
Port 3 is Common.
Compressor (red) should go to Port 3.
Wastegate (yellow) should go to Port 2.
Intake (blue) should go to Port 1.
It is very important that your Compressor / Wastegate be on Port 3 / Port 2, respectively, which is the normally open configuration. This is in case of solenoid failure, the boost levels will revert to wastegate spring pressure. If you use IPD's configuration of Port 3 / Port 1, respectively, you will be using the normally closed configuration, which means in solenoid failure, you will have a no boost pressure reaching the wastegate, and it will overboost and most force your ECU into limp mode. That sudden spike of boost could also be detrimental to your engine's internals.
The stock TCV also uses the fail-safe design of normally-open.
Please verify that you are running the right configuration!
