    Default Injector Data for GM 12561462 ('04 GTO LS1) & GM MAP 16212460

    I've been searching for hours reading threads, and still haven't come across this data. This is a stock LS1 injector from a '04 GTO. Not sure why it's been so hard to find. Does anyone have these numbers? Thanks.

    GM 12561462 injector: 25 lb/hr @ 43 PSI, High Impedance. GM rates this for the GTO 5.7L (2004) at 28 lbs/hr. Same thing +/-
