RPM goes 0..8000 in steps of 8000 (see what I mean)
Then enable the MAF, drive and log, and then use this map to apply filter and corrections ("paste-with-multiply") to the MAF table, very much like doing the VE table.
But first, like TA said, make sure your VE table is dialed in.
If you can't hit > 4k, then cheat by setting the "hide low cell count" value to 10, but use common sense.
