I'll admit that was not very thorough, since I only looked at the .bin file's VIN.
Looking at the file's calibration number directly, yields 16199871, which is, so far as I know, not a GM calibration part number.
It does not rule out the possibility that the original .bin file was a 4.3L L99 .bin file, with pains taken to transpose all the 5.7L LT1 values into it so it would work well with a 5.7L LT1.
I apologize for the distraction. Fine-tuning the injector data should make this .bin file work more than well enough.
