    Quick google search

    Here are the specs on the 42# injectors I had. They were commonly know as 8.1 Marine Injectors.
    Part Number 17113739 (OE Part # 25176061)

    txt files are supposedly from a hummer with supercharger on it.

    Sorry to bring up an old thread, but I'm in a similar situation and Magnacharger can't/won't help with the 17113739 injectors. I need the all numbers for an returnless style fuel system that I'm running with my Maggie. Thanks in advance.

    Those tables are sloped...

    IFR table is sloped with close-enough sqrt(pressure/pressure) relationship.
