Stock M90 is what, about 7lbs. of boost. Colder days, you may see a little more boost.
Safely you can run in the range of 12-15 lbs. with no problems, but you HAVE TO RUN SUPPORTING MODIFICATIONS TO SAFELY RUN THAT.
Maximum boost...I think it boils down to how much the heads/head bolts can handle. That seems to be the weak spot on our engines. Too much boost, the heads will lift up enough because the bolts/studs cannot hold them down...enough/evenly and ''poof" there goes your head gasket.
I have heard some of the turbo guys in the 20 lb. range easy enough.
