What variables affect 2 byte load calculation?

Sorry to bring this thread back, but it is very interesting.
How does a stroker (2.1, 2.2, 2.3, or 2.4) change the load as calculated from the MAF? I ask because I tuned an Evo 6 with a 2.2L and 1mm oversize valves and it reads about 10 to 15 higher loads than expected (compared to a similar car with a 2.0L).
I understand that for a "normal" setup 0 psi should correspond to about 100 - 110 load, what if 0 psi in this car was now 120 - 130 Load? Could this be calibrated by changing MAf size or other maf related parameter so that the stroker will correlate better with the maps? I mean NA behaviour reaching about 100 load and FI starts from then onwards.
Cheers,
Ricardo
