I test my surge to 30psi as well, and it's never been a problem. Only problem i do have is blowing the pink line off under high boost. I had to double ziptie both ends of the pink line to make it stay put.
I ran the times in my sig with a stock surge valve, no blue plate, all stock vacuum lines on still.
Mind you I HAVE blown out 2 surge diaphragms before. On bone stock turbo no less, and not on my more powerful turbo setups. Try to figure that one out, lol. There are cheap replacement kits on ebay, though, so no worries.
