Im running 15psi with the stock MAF. It can be tuned, but once the MAF is maxed out, the tune resorts to dumping a specified amount of fuel based on RPM at WOT, not actual measured airflow from the MAF. This is more or less a bandaid approach, but if your car is supercharged then its not really all that bad since boost will come on linearly and predictably every time...

If thats not an option for the OP, then I'd suggest tuning it in worst case scenario conditions and then only thing is in better temps, it will be a little rich. 
We can do E38 speed density tunes, just a little math involved and it takes a bit of time. We can do 2, 2.5, and 3 bar tunes on them.
Here is a dyno sheet from a cam only 5.3l with a E38 ecm speed density open loop.

I have seen 15psi before on accident...after dyno and forgot to spin boost reg back down. I usually see 11-13psi on the street fwiw. But my snow meth kit uses a maf freq controller which adds meth based on flow even after the stock maf maxes out. I can set my timing map of course so as long as my WB reads rich, then I don't worry about anything other than my stock long block.
