For tuners, a Holy Grail of Injector voltage Offset

I can't speak for other tuners although having looked at calibrations, many don't approach these parameters. Some might do "workarounds". A good number of these parameters aren't defined in the .xdfs or .tdfs generally available.
Finally, it takes time and gas. I'm pretty finicky about how I want the car to react to inputs, so I probably spend more time than necessary. But its getting easier because as we develop "standard" configurations for modified LT-5s we can at least start with a calibration that's in the ball park then fine tune from there. Don't need to constantly re-invent the wheel. As an example, I was able to use the tune on my 5.7L and translate for use in a 6.2L because of similar porting, cams etc.
Hope that answers your question.
