On my EWG, with Grimmspeed EBCS, I run the 10.5 PSI spring combo running 20 PSI on a VF43. My wastegate cracks at 2800 RPM and is fully open at 3200 RPM. Never had over boosting and have a near straight line that slightly tapers down throughout the RPM range.

My car peaks at 20 PSI.
I was only going part throttle in that video showing how it opens. I wasn't anywhere near full throttle.

I am currently running the 11.60psi spring combo (according to Tial). Based on what my boost gauge is telling me, it is actually a 15-16psi spring combo.

In response to kellygnsd, I don't have trouble keeping my boost down anymore. My issue now is inconsistent boost. I set my manual boost controller at 19psi, than the next day it will be 1-2 psi higher or lower. So what I'm asking now is will an ebcs keep my boost more consistent?
