Not to be a dink but you've already asked this question and got your own answer.

Just open a 6.2 tune and look at the flow rate table, it will tell you exactly how much fuel pressure the factory injectors are rated at. You can view both 44psi and the factory 58psi that they are rated for.

At 3 bar they are 44lb/hr, at 4 bar they 50-51 per the injector flow rate table.
