Default Newbie question- maf and injectors

Hi Guys,
I have a question that is probably second nature to most of you. When I uprade injectors do I need a matching maf also? I am planning to get 50 or 60# injectors for a supercharged set up of a 95 gt.
I am assuming if I get a maf matched to the injectors I wouldn't have to reprogram the ecu right? Or do I?

Thanks for the help!

Yea definatley a new Maf cause those are some big injectors. And if you want to have a good running car, might as well spend the money on getting the car tuned if you can, or else in my eyes your gonna waste your time on a supercharged, fuel injected car. If you get it tuned by someone, it should be a good running car.

I think you would only need like 24lb injectors...cause 50-60lbs is way too much.

yes, i think certain mafs my come calibrated for different size injectors, just make sure you change out your fuel pump, and possibly the regulators, and just keep an eye on the fuel pressure, dont wanna run too lean or too rich
