So if you put an 8psi spring in the gates, you may see 7psi at the manifold due to the 1psi drop across the system.

So, what you can do is run the boost source to the lower ports of the wastegates from the nipple on the driver side charge pipe (this is the port available in the kit). Then, instead of plugging the port on the compressor, you can run it to Port #1 of your solenoid, and then from Port #2 to the top half of the wastegates.

This configuration would work perfectly fine.
