    sep 850 inj info needed. bear with me im struggling..

    ok boys .
    5.3 /th400 sep850s
    slopy stage 1 elgin cam , billet 78/75 vs turbo.0411 pcm 3 bar os
    ls6 map sensor. pump gas
    Im really struggling finding a tune for this combo, seemed pretty common. Im pretty new to hp tuners and finding my way around.
    I have it running and just threw som big numbers t the +105 kpa table.
    seems to me the first step besides failing the maf is enetering the injector info. so far I just entered 85lbs per hour across the board n left everthing else alone.
    does anyone know the proper injector values to enter? the 850s cae to me n.ib but second hand. I have the sheets that came with but they seem usless to me.
    can some one point me in the right direction for a tune to get me closer , im worried about the fuel n boost timing, cant afford to po this thing learning. I have a wideband installed and once I can start logging I feel like I can get it dialed
