It seems like Mustang owners more than any other hobbyist group loooooove to pump more fuel into their engines
Although my knowledge of engines is pretty elementary, I always assumed you increase the injector size corresponding to increases in air flow (intake, heads, etc) Am I wrong? Because I don't see where enough flow in your setup would even come close to requiring 30#, even 24#. I dont have heads yet, but with my setup I'm fine with 19#
