Abaco [(877) 883-1717; www.abacoperformance.com] super-rad DBX air meter was, without question, the most talked about EFI Mustang (’89-to-present) product introduced at the PRI show. Available in 85mm and 97mm versions, the revolutionary new digital mass air meter holds as many as 10 different injector calibrations that can be changed by turning a small switch or downloading new values from the Abaco Web site. Gone are the days of sending a meter back to the manufacturer for recalibration or making ECU adjustments to compensate for bigger injectors. This thing is hot. Nuclear hot.
