Mass air flow readings

Hey everyone.
My tuner is showing a max air flow of 287.6 g/s. Seems like guage is reading fine as it shows anywhere from 140 to 287.6 g/s at highway speeds depending on engine load of course.

So my question is, does the tuner only read a max value? is that all the air flow that is allowed through my system?

Even after the max value is reached, I am still gaining power, spooling boost, and have no problems I can tell with running of the truck. Seems fine, just caps at 287.6 g/s.

I have a S&B cold air intake installed, which could use a cleaning, but is still not bad. Could this max reading indicate restriction through my filter?

Other notes:
2008 F 350 6.4L
DPF Delete, Cat delete
Evolution Racing CTS Edge Tuner - Tuned to PL4 at the moment - Usually PL 2

Any ideas?
