MustangWorks.com : Ford Forums - View Single Post - cheap way to upgrade to a 73 mm MAF meter

So I got a T-Bird MAF for $5 Canadian, almost free! Now I just will have a problem calibrating it, since drilling out 15/32 works for a supercharged 5.0 which needs more fuel it may not work well for naturally aspirated 5.0

Any ideas on how to do this??? I was thinking of buying a fuel pressure gause, air/fuel mixture gauge, and an adjustible fuel pressure regulator.
Would increasing fuel pressure mean that I would not have to modify the MAF???

Would it be better to play around with the sampling hole in the MAF -OR- buy a "variable resistor" and play with the voltage coming out of the MAF sensor???

If we get this idea working properly then after-market MAFs will be history.
