Twin Scroll Wastegates Springs Pressures?

[1gDSM4g63]

I'm about to setup and divided T4 turbo with a twin scroll manifold that runs two Tial 38mm wastegates and I'm intended to run at least 30 psi. of boost. I have idea what spring pressure ratings I need for the wastegates. Should it be the same as nondivided, 2x or 1/2x the pressure rating?

Same as non-divided.

So will 1 bar springs for both wastegates be fine for 30 psi?

I'd go a little under whatever the least amount of boost you think you'll need to run.
