ABACO Performance offers the only Digital Mass air meter on the market today. Their DBX meters work great with draw through or blow through applications. They also offer a patent pending Built-in Digital Response Filter which is used to filter out much of the "noise" associated with the mass air flow sensor without sacrificing response time to air flow changes. This, in-turn, dramatically improves drive-ability with those experiencing camshaft intake reversion or pressure surge (for turbo and/or superchargers).
