The short answer is no, the 94-95 MAF will not require any extra tuning that the stock 55 MM MAF would have.
None of the OEM MAF's are calibrated for any size injector. They report airflow volume to the EEC. The idea of calibration comes from the aftermarket.
That said, to make this understandable, we will say the stock 55mm A9* EEC's MAF is calibrated for 19's. The 94-95 MAF (any stock MAF from a GT, V6 or Cobra), when used with an A9* EEC, is calibrated for 19's.
If you want to run 24's, you need to either tune the car (just as you would with a LMAF or any other factory MAF not using the injectors and EEC that were married to it from the factory), use an aftermarket MAF, or use a device that changes the MAF transfer curve (there are other more obscure options as well).
Think of the 94-95 MAF like the stock 55 MM Maf. If you used 24's with the stock MAF (and kept your current EEC), you'd need to change the MAF. The same is true with the 94-95 MAF.
