Default dual wastegate thought

What would happen if you had two different spring sizes in each (10.1psi & 11.6psi)? would you boost the average of both springs? just something i though about trying since i only have two of one size spring.

I could be wrong but I dont see how that would work.

One gate would open at 10.1. Youd only make more if you were getting boost creep before because that gate couldnt keep up, then youd get the 11.6 before the other gate opened.

The lowest spring is the pressure you would see.

Unless the smaller springed gate was unable to flow enough to bypass, then boost would be erratic..

In my case i would see the higher of two springs due to one wastegate not flowing enough for my set-up. I was over-boosting with only one wg.
