Mass air flow readings
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?
