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.
this kinda contradicts its self. your saying the MAF can make the corrections and thats it! but then you say the tuner needs to adjust scaling. so ill hold what i said first. the MAF can adjust BUT not much! thats why you cant throw in 1000cc injectors and be ok. why you cant add a CAI, DP, header, UP CBE and be ok. i put on a CAI with no adjustment and shot up to 33MPG. the car was WAY to lean. the AFR and scaling still needs adjusted because the MAF CANT do it all.
