Sorry for my ignorance but What is a MAF calibrator?

I know MAF is Mas Air Flow wich mesure Volume of air. But never heard of a calibrator.

 

My guess is it 'calibrates' the maf sensor to think less air is coming in, therefore less fuel will be used. Leaning out your engine will likely decrease the life of it though.

 

I don't think it only leans the mix. It is a mappable interface that takes the signal from the MAF and allows you to tune it to clean up several different issues and/or use some of the power that the stock ECU doesn't access because of conservative tuning.
