I have a MAF meter from a sn95 the number is F2VF-12B579-A1A. My question is can this work with 24lb injections? I know it's calibrated for 19lb injectors.

Oem MAFs aren't calibrated. The "calibration" for an aftermarket MAF is to resize the sample tube to trick the ECU into seeing less air than it is, signaling the ECU to injection less fuel with the larger injectors.

If you want to use 24s with the oem MAF, you need a tune. If you don't want to do that, then you need to buy an aftermarket MAF and fool the ECU

Thanks Mustang5L5 that makes sense.
