I am thinking about getting a bigger mass air and throttle body, this will give me more air, but how do I get more fuel though? Are there bigger injectors I can run, or fuel pressure regulator like on a 'Stang? I know a reprogrammed chip for all of those mods will help too, but if ya cant get more fuel, its worthless. Also, are there any high performance heads or cams for a 5.4L.
