Simple MAF?

What is actually measured to say a MAF meter is 65, 70 or 75mm? Is it the bigger opening on the end of the meter that is measuring those numbers? What is the best MAF meter to use for 19lb injectors?

How about a little more info about why you're asking about larger air meters. Are you changing injectors, supercharger, motor rebuild, etc......?

All I want to know is basically what is being measured to say it's a 65mm or 70mm MAF meter I am not upgrading anything? But since we are on that topic what is the better MAF meter to use the cobra 19lb calibrated meter or the stock F-150 94 MAF calibrated for 19lbers?

I believe that would be the internal OD of the tube in millimeters.

The ECU's transfer function is how well it will or will not work with another MAF.

If you're refering to a physical measurement then it's the inside diameter.

Thanks for the correction Matt. In my response there is no such thing as "the internal OD" as I stated. I meant the internal ID of course.

Can you not change this function with SCT tuning software or Tweecer??

i.e. Could you calibrate a stock cobra and/or truck MAF (OEM 19lb calibration) to let's say ..... 24lb'ers via the tuning software??
