The DiabloSport MAFia F7370 provides real world plug and play control of your vehicle's Mass Air Meter (MAF) on 1996-2004 Ford Gas Applications. Mafia allows you to precisely control and regulate MAF sensor voltage eliminating the need for Pre-fabricated custom MAF sensors. High horse power applications require custom tuning, or for stock applications the MAFia features 5% lean 5% rich The MAFia uses factory connectors and harnesses to attenuate the signal to a vehicle's MAF, and allows vehicles with stock MAFs to run beyond the standard 5 Volts. When a vehicle normally reaches 5 volts, it "pegs the meter" or maxes out the signal, keeping the vehicle from making peak horse power at high RPM. . The MAFia attenuates this signal, and will allow a vehicle to make up to 800 RWHP without "pegging the meter. "
