well I was thinkin about changing my maf to a 75mm a while back with a 70mm TB. Someone told me to go ahead and get the 19lb maf anf if I get new 24lb injectors later after my H/C/I swap that I wouldn't need a new maf, just too take to get it dynod and they could tune it to match up. Just saying what I've heard.

No you do not... you guys have no clue what you are talking about.

It is always a good idea to upgrade your MAF to one that will read better at higher flow rates, but you do not have to get a MAF that is calibrated. Infact, you are better off NOT buying a calibrated MAF, and letting a dyno-tuner adjust the values in your ECM instead.

+1 you dont need one right now, but if you happen to get one Pro M makes a good one, but their out of business. However some tuners wont tune without a calibrated MAF for some reason

Exactly. However, MANY fox owners forget about the fact that the SN-95 comes equipped STOCK with a 70mm MAF. So upgrading on an SN-95 isnt as important as on a fox!
