MAF calibration
 

So I got a 73mm T-Bird MAF for $5 Canadian, almost free! Now I just will have a problem calibrating it since t-bird had grey injectors not 19lbs.

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 to increase fuel delivery???

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???

Any help would be appriciated, thanks.
