What is the stock mass air meter??

For a 99-04 gt, is it 80mm calibrated for 19lb fuel injectors?

i think 99-01's were 70 or 75mm and 02-04's were 80mm, but i can't remember for sure. but anyway, newer Ford Mafs are not calibrated for any size injectors.

Like DBMSTNG said, they are not calibrated to injector size, the EEC is. 99-04 were 80mm, but 02-04 had an outside lip that was 85mm if I remember correctly.

but either one could be used in a stock 00 mustang?

The curves may be different. I don't have a later model to compare it too. Also the later models had the ACT sensor built in to it.

what about getting a maf out of a 96 gt +? Are they all 80mm?

if your looking a for a new one just get a 90mm L-MAF... they are like 70 bucks on buyfordracing.com

But unless he has the ability to change the MAF curve in the EEC himself, you have to add the cost of a custom tune to that.
