Great thread!!!!!!.......didn't undertstand all of it.... but some very useful info....
At least now I know that a stock 335i has about 8psi and the the only mod i have is a JB plus which will give me an extra 4psi .....and total comes to 12psi....and by what you guys wrote...I'm in the "safe" zone.... :-)
as a general guide, should we say that anything above 16psi is "a bit risky"....?
