I have run 14psi quite a bit on my lq4 on a e30 mix, ran it on 18psi before but have not yet again,as long as you have a good tune and all the saftey you can add 18psi is doable

There is really no limit. It will brake at some point. I say boost it till you get the numbers you want then see how long it lives lol.
