    L76 IFR table HELP?

    Hello I am going FI on my truck. It is a 08 E38, L76 6.0L set up “vortec Max” I will be using a turbo pushing around 8LB of boost. This is what I have calculated so far using these formulas

    New power = [ ( NA power / 14.7 ) * amount of boost ] + NA power

    Turbos : LB/HR = (Desired HP * .65) / 6.4

    I get 567 HP at the motor so using the other calculation that dictates I should need around a 58LB injector.

    I know these are very loose numbers and this is all dependent on fuel pressure and injector flow rating etc. I plan on using the FAST L76/L92/LS7-Type Short, EV6/UScar, 65 LB/hr injectors for room to grow. Now this is where I need help. I don’t know much about the new L76 vortech motor as far as its fuel pressure etc I believe it is a constant 58LBS, and I also have not been able to find what size injectors are stock in this truck. All of witch I assume I need to know to set up my IFR table. I looked at the sticky above but it appears that spreadsheet is set up for something completely different. My table for IFR starts at 128 KPA.. Can I simply ( (new injector size / old injector size) = X ) then (X * stock IFR table) ??
    Any help is appreciated I want to make sure I do this right and learn as much as I can while doing it.

    edit make thoes 50LB injectors due to the E38 IFR maxing out.
