Second, as I have told you before, these are not the GT500 injectors. Different part number, different plug, different length, different flow. The only thing similar are they are made by Bosch.
Third, we have good data for the LSJ for these now, as I have spent hundreds of hours making the correct offset tables, and they are verified to be 100% correct. I could care less about the numbers that someone comes up with on a bench for injectors for the LSJ, because they simply do not work in these cars. Take the Siemens data in your table, and do the 10% fuel test. I got 5.1% change with that data. The data in your worksheet is correct for every other car made, just not the P12 LSJ platform. Something in this PCM OS is weird and uses 50% of the offsets.
And now that I think about it, the 2006-2012 57# and the 2013 60# GT500 injector would be a very good choice for these motors too, and there is good offset data out there for them already. Greg Banish himself put that data out.
And as far as the Fuel Injector Connection thing, they hire someone to transpose the offset data for them. They measure the offsets, then have someone chart them out. I really do not know exactly what happened since i have seen that write up. If you buy these injectors, guess who made the offset tables that will be emailed to you from FIC? Me. I made them with hundreds of hours of trial and error, for free.
I would rather you did not call my work "junk", because it isnt. The simple test on any injector data is simply add 10% more fuel, and see of your actual AFR follows. With my numbers it does exactly. I have done this for the Siemens 60's, Siemens 80's, and the Bosch injectors I have. I am simply trying to save people some headaches and make the LSJ tuning process alot easier for everyone.
