Quick sanity check...With the above diagram if i am running a single turbo with two waste gates what is the best way to plumb it? I would assume just y the gates together going to the solenoid and split them from compressor to the gates. Basically y both lines. And i would only need one dome pressure sensor on one of the gates right? Thanks in advance.

Yes of course just run y's or t's. Thats how my dual wastegates are. 1 boost reference port

Follow the instructions of whatever controller you are using. There is no generic "best" given the many configuration options that exist.

I'll still never get why the US systems need to use 2 solenoids to do the job of one.

By the diagram I'm assuming you mean pressure source? You are able to use co2 or compressed air with the solenoids. Both gates should have the bottom port to the compressor discharge.

This is the diagram for the Holley boost controller solenoid. They don't have a recommended setup for dual wastegates in their instructions.

This issue confuses me to no end. You tee the compressor discharge to the bottoms but you also need for the tops (pressure source).. not using co2 or anything... now you tee that compressor discharge 3 times? Is there someone that has the holly efi ecu running 2 3 port solenoids and dual wastegates?

I'm haven't got mine running yet but here's how I'm doing it.
