has anyone had any issues with regards to tial wastegates allowing for more boost pressure than rated for?

I have a dual MVS setup with 1.3 bar (18.85 psi) springs (grey/gold/brown 8.7/5.8/4.4 psi respectively) and at 0% wgdc i am holding 24 psi. I would like to make a 22 psi road corse map. I pulled the brown spring out but i haven't yet tested the car.

has anyone else made considerably more boost than rated when running only wg spring pressure?
