I see fully bolton + corn running 29 PSI on stock valve.
Even the "smaller" turbo packages don't mention needing an upgrade.
I don't think it is necessary at all unless you plan to build your engine and get a massive turbo.
I am curious though how much PSI the stock one holds until it leaks.
My EvoX was about 26PSI until I had to "crush it" and eventually replaced it with a WORKS one that had a heavier spring.
