do i really need bigger injectors or will the stock ones work. does a bigger maf really make a difference. bigger throttle body make a difference. fuel pressure regulator. im in this area right now and i dont know which one to get first

it depends on the mods that you already have, if you have and intake manifold and heads and a cam it will make a difference. I have 30lb injectors and a c&l 76mm mass air calibrated for the injectors with afr 165 heads, system intake and a f303 cam and on the dyno my air/fuel is perfect with my 70mm throttle body.

Yes it will make a difference. Especially if you already have work done to your car. Just to let you know also, if you are running 300hp or right around there you should get some 24lb. injectors and have your mass air re-callibrated.
