I don’t know maybe this is old news but with everyone saying that you need bigger fuel injectors I thought I would post a link to these anyways since it was the first time I saw them.

True more fuel = more power but in the case where you're ignitioin timing stays the same and the amount of air coming in does not change much I don't think you're gonna see any gains from just slapping of bigger injectors. Also, our ECUs are self learning so if the amount of air coming in change a bit it will increase cycle duty to your injectors. Most injectors are running well below 100% to prevent it from injecting stream of liquid instead of mist.
