For anybody interested, here's my experience upgrading away from the old generation C&L 73mm MAF I've run for years to the modern era of MAF technology using Ford's Slot style MAF sensor stuck in a piece of PVC pipe.
Custom intake track for slot style MAF sensor

Note, this isn't possible without the ability to edit the tune in the EEC. But it shows what's possible.

I did something similar on the Cobra. I first changed out to the SCT BA5000 slot sensor but found the resolution at lower RPMs wasn't very nice and it'd idle at inconsistent A/F ratios. I then switched to a stock 07-10 GT500 sensor and idle and low end drivability is way better. I haven't had a chance to tune up top yet and see if I will run out of MAF and need to use a mafia or not.
