Yep. Just checked my HPTuners log file of my stock bin. I used to have 28.8lb/hr injectors and the stock bin shows up as 28.15lb/hr. Given the 4-bar fuel pressure of a stock LS1, I stand corrected - GM rates their factory injectors at 4-bar.
So the 30lbs injectors will deliver 43.5lb/hr at GM rated fuel pressure, or approx. 50% more fuel delivery.
