a mafless tune is a tune using a MAP sensor and not a MAF. Your buick only has a MAP sensor so technically u already have a mafless tune

mafless tune originated from the LS1's, they run both a MAF and MAP sensor, and you get more out of the tune just by tuning using the MAP sensor, hence the mafless tune.
