G56 swapping my 08 6.7 pickup non C&C and I need a stock unmolested tune file. What happened to that website that used to have a bunch of stock files for free download?

ok finally got around to this, checked that link and now im wondering if operating system/calibration matter? like do i need to match any of those with what is in my current PCM or does it not matter? just change the vin and good to flash?
