statesman is correct, using LTFT's provides a coarse correction, look at the LTFT 4x4 array of cells that covers the MAP x RPM range;
usually LTFT's work ok in Calc.VET when there is very little change in an LTFT cell;
but it looks like your case requires trimming disabled (including B4206), use CALC.WO2BEN to apply corrections to MAF...
you will need to correct VE separately on similar manner.
