.028 for stock. I run mine .025.

Mine is b/t 155-165psi across the board. From what Ive seen, mine is on the lower end of things, but still good within each other. There are more comp threads on SF, might wanna check there.

hmm why such a small gap?

The smaller the gap on the plug means less chance of blowout if you're running higher than stock boost.

Interesting. What is your setup and when did you notice blowout? I might take mine down to .024 just to try it.
