I'm looking to buy a set of 38lb injectors and matching/calibrated Pro-M 80mm MAF for my 2001 GT. It is coming off a Fox Body 5.0. I know the injectors fit, but will the MAF? It is not the stock MAF.

This will be used for a supercharged setup so yes, it will be getting a new tune.

Calibrated MAFs are not a good idea on 94- newer load based PCMs , they throw off the MAF values to compensate for the injector change , this throws off every air/flow/load based calculation that the PCM makes , get it tuned for the stock MAF and the 38s ,or you can run a lightning 90mm MAF but you will still need to get it tuned for the injector and MAF changes

I don't think the stock MAF is capable of metering enough for a supercharger setup ... even on a lowboost setup. This is a larger 80mm unit.

My stock 02 GT stock MAF was good for 8.6lbs at 372rwhp

Really? I just heard from numerous sources that the stock MAF will max out around 300whp.
