I would stay where you are at with boost, and just add some squeeze to the mix!!

Talked with Erik at HK engines and he said I will be fine at 18psi. No problems.

I would say your fuel system is going to determine how far you go on boost. I'd like to know how far myself since 12lbs feels slow already.

The meth is supposed to help take the load off fuel pump.

Is he going to replace the head gasket if you pop one??? You would def be pushing it at that psi with out studs... If you had them, then it would be very doable..
