Actually, yes. Just yes. Note "yes, but..."
Just yes. That is what MAF-based fueling is all about.
The MAF sensor's job is to let the ECU know how much air is flowing into the motor. If it can't do that accurately, something's really f***ed up. The tune either needs a MAF scaling adjustment, or (and I really doubt this was the case here...) the MAF sensor needs to be put into a bigger housing.
