to answer this question, a pcm tuned for a boosted motor will run off boost and boost (over 100kpa at sea level). But you can't run a pcm tuned for just n/a and boost it because it will :bomb

Actually,
You can run on the stock tune, with low boost, 5,6 o.r less psi.
But u will need an fmu, return fuel fpr at the rail,larger injectors and fuel pump upgrade at a minimum. Many sc/tc kits were sold with a fmu for fuel enrichment under boost. so is it possible, to run on the stock tune. With or without boost, since the fmu provides a huge amount of fuel pressure/volume at the injectors. But is not optimal for a real high hp motor.
There is no real substitute for a proper tune, and a return fuel system with a rrfpr for a serious forced induction build and a complete recalibration of the tune. No way around it.
