What maf to get for the vortech s/c kit

I'm going to be installing my vortech s/c here pretty quick, but I still need to get a mass air meter that is calibrated for 42lb injectors. Do I just need to get a maf that is the stock style with the flange on it calibrated for the 42lb injectors?
 
Nothing wrong with Pro M, I would rather have one of those. I figure there is no place that is going to have any new ones, and I would have to try and find a used one for my application. Just figured I could get one quicker if there was another company that made that style.

I'd put 4" afm powerpipe and 90mm lightning,,the 80MM is smaller diameter then the powerpipe,,the 90mm is better suited for 4" powerpipe..
