MAF and injector change

[jwmustangin]

I have a 2001 gt with the manual trans and everything else pretty stock except for the pulled air silencer, flowmaster series 40 mufflers and the steeda pullies and timing adjuster combo.

Would I recognize any change if I upgraded the stock 19lb injectors to the 24lb injectors with a new 80mm pro-m and a 24lb calibrated MAF? How much improvement in numbers would I see?

If I did this would it affect a 75-shot NOS install for the better or for the worse? How much improvement would I see, if any? I would probaly turn my timing back to the stock 10 degrees if I did the NOS install.
