I have a 2000 LS1 and when I download other peoples tunes especially 2001+ and I try to do a compare with my stock tune it tells me the operating systems are different and cant be compared..Why?
Also, could I just flash my computer with a 2001 OS and just start from there? There are a few tunes that have the same heads/cam and I would like to try and use them.
Another question, There VIN is different then my of course, but does it cost another license to be able to us their tun file?
