    Bosch EV14 0280158117 (Injector Gurus help!)

    I purchased a set of these 0280158117 Bosch injectors and it have found out that they're m-9593-g302, Ford GT500 injectors, 47lb at 39.15 PSI These seem promising at 58psi and above. The problem is, all the data that I can find for them seems incorrect. I've found data from Ford Racing, Muscle Motors but it all shows the same info. I've read that Ford is known to do this.

    Please look at the calibration summary, in the fnpw_offcomp section you'll notice that the multipliers look wrong, they are not even in line at 30.02 and 60.03. When these numbers are punched into Stecks spreadsheet the offset vs VAC vs Voltage section shows negative values in the 70-80 kpa areas. I have to assume this summary is wrong..My main question is, how do I figure out what the heck these real numbers should be and where else might it also be wrong?

    It should prob be noted that if you convert the the alosl (low slope) to lb hr, it shows 57.28 lb hr and on the ahisl (high slope) it converts to 48.58. So I'm not sure if those two should be trusted either.
