Bigger injectors on stock engine?

[USMC302]

Well, first you would have to get the tube that goes along with the injectors for the Mass Air meter, which will be costly and without heavy mods or at least 350 horsepower you really don't need that big of an upgrade. Your computer would most likely adjust anyway to keep the right fuel/air mixture and you would not see any benifit from the 30's. They are good supporters of horsepower and make room , but they are not producers, kind of like pulleys. if you plan on spraying or boosting then I would say go for it. they would be needed to support such an application.
