John, thanks for the introduction. Very nice to meet you. My name is Jon and I have been a BMW freak for a long time now. I have 3 bimmers: 99 e46 323i, 98 m3 vert @ 8psi, and the work in progress 91 318is we are currently discussing.

My goal is 15psi - 20psi. 15psi would be "daily" setup and 20psi to have some short fun. What would you suggest stock valves or upgraded?

So, you wouldn't suggest touching the head in terms of a port/polish job?

Thanks.
