I have a simple question

the stockers are pretty good for most of the plug-n-play off the shelf cams with stock heads, stock cubes, etc. When you get into some serious heads, intake, etc then of course bumping the injectors up helps (all synergistic). People tend to sometimes over-do with injectors too soon and it hurts your tune so bad you can't sit in your car at the light let alone back into your garage.
