Forced Induction for Dummies (Turbo, Supercharger, Nitrous)

NA MAF to FI MAF; is one of the harder processes to do IMO.

But I think the primary reason for that is the "newness" of MAF based Tunable EMS's - which are basically Flash Tools like the Cobb AP.

The upside is that since MAF = MASS of air; you don't have to account for heat from FI for fueling purposes a.k.a. Loss of PPO2 due to heat (you do for timing obviously; as a super hot intake charge will be more likely to detonate).

I am pretty darn sure that MOST of the factory boosted EMS's (MS6, MS3, EVO, STI) - have both a MAF and MAP; which would a really good way to tune; hence why the Oem's use them both.
