    Default Injector flow rate

    Hi guys. I put some injectors in my 04 Silverado SS with the 6.0L from a 04 Sierra 8.1L. I copied and pasted all the injector info from the stock 04 Sierra tune into my tune. I heard they flow at 29.9 lb/hr. So I was going to check my values with RedHardSupra's excel worksheet and with my fuel rail pressure at 58 lbs, and my injector rated fuel pressure at 43.5 lbs. I put in 30 for my injector rated flow rate and for the new information from his calculations.
    Should I put these values in B4001 Injector Flow Rate?
    My old values ranged from a 29.3903 lb/hr @ 0.0psi to 32.3665 lb/hr @ 11.6psi.
    I have not reflashed my pcm to the RHS values yet.
    Thanks for all the help.
