Yes thats what I think is limiting you.
BTW, you extended the axis of the MAF linearisation map? There is no point in doing that, you cant extend the measuring range of MAF by that.
Well you can make a test. A simple log file. Engine speed, air quantity (mg/inj), and MAF voltage.
Then make an acceleration in 4th gear or higher from 2000 to red line. Then you will probably see two things. One is that MAF hits a "plateau" at lets say 4.8V, from certain RPM this voltage will be constant (limit of the MAF). And then you can then calculate from mg/inj into kg/h. And you will probably see that airflow does not reach above ~570kg/h.
