Ok I'm confused. I understand that the stock MAF maxes out around 450 g/sec and that the PCM basically won't read any higher than that (correct?). By adding the new MAF to allow for boost, what do you do with the fuel tables under boost or do you use an FMU? And since you are using a stock PCM, did you get a higher rated MAP sensor? Does Tunercat or the like allow for modifying the fuel tables for higher MAP readings?

Not quite...
The idea of a bigger MAF like the PRO-m is that the maf will not max out at the same Hz as the smaller maf... hence you will have a shift in "resolution" that way you can have "metered" air and tune around it...
The pro-m has an output voltage of 0-5v and it needs a converter.. im not sure if the one for GMs has the circuitry in Hz output.. which was one of my main concerns.
