Yeah.. I know only one MAF, lol

What I meant was, when I got my truck, it had a remote mount turbo and such, and some issues... I stripped out the turbo setup/piping/etc, and during the process of pulling parts, replacing stuff, etc... I ended up buying a MAC intake as I had no stock intake or anything, and the MAF tube/MAF that was in the cold side piping would not bolt up correctly to my MAC intake heat shield dealios... So, I looked around and found like 3-4 different MAF tubes, one fit, and I'm not sure what MAF was in the MAF tube, as, there were something like 2-3 different MAFs floating around at that time lol.
I was wondering if by looking at the MAF (don't have one in front of me ATM as I am at work) I can determine which MAF I have.
I have 39lb cobra injectors on the truck (left over from turbo time) and want to be certain I have a MAF for those injectors and such and everything matched up for when I get re-tuned.
Sorry for the confusion... Kind of hard to explain lol.
In addition.. I am wondering if
