On 3 Performance 05+ Slot Style HPX Maf Kit

(1 customer review)


On 3 Performance is stocking the new style 05+ HPX slot style maf kits to run on your 87 – 2004 Mustang in a blow through application.  This kit will come with the HPX slot meter, your selection of steel or aluminum flange, as well as the pigtail to wire it in.  What makes this maf a great option over the earlier style that most people sell is that its very compact, has a better signal for tuning and also has a built in IAT sensor.  That way you can wire it directly through the maf and no need to weld a bung for an additional sensor or have to rig your factory sensor into a boosted application.  When doing that you risk blowing it out of the pipe and turning into a boost leak.

    Like the meter just wanted to know if its calibrated already or part of my tune???

    • admin

      The meter is calibrated / flowed directly from PMAS which is why it will support the power and airflow in a 3″ tube but its not specifically calibrated to each specific injector. When tuning the car, your calibrator will be making the changes to the ecu and this is all standard run of the mill work for custom dyno tuning. The HPX Slot meter is unlike the old school “drop in” meters that would have a specific injector calibration although you still need a custom tune to fully finish either install. This is basically Fords newest Mass air technology that you pair up with our pigtail and can use on any of our V-8 Mustang applications from 87-2010
