Most GM MAF's max out at 11,000Hz. It's just how they built it into the pcm's. How much air flow that actually is depends on the size of the MAF. If you max out a MAF you can get a bigger one from another engine (say an LS1) and take the MAF values from that and put them in your MAF table and re-tune the pcm for it if you have a tuner.

MAF doesnt measure PSI, thats MAP. the MAF would turn to CFM from frequency, but also has to do with the density of the air alsoComment
