Based on that reading. 1990-1992 tpi automobiles converted to a map system (also called velocity density) wherein the ecm gets a expected air waft based on engine vacuum. The alternate to map is rumored to be primarily based on value reasons for gm, but for performance engine builders, the confined air glide capable of skip through the maf is also a consideration of changing to a map gadget.
