Message	If it was just a matter of tuning then you wouldn't have 270cc NA injectors and 370cc TT ones. Idle MPG Driveabliliy reliability My best guess is that Nissan engineers wanted injector duty cycle in some "sweet" spot for their given application. To this day you don't see car manufactures grossly over size injector flow rates vs projected stock engine needs. Can a NA run on 740cc injectors - yes. Is it a good idea - imho no.
