Good evening guys, I stumbled upon this forum after doing a cam swap on my 2008 GMC sierra 4.8 LY2. The bummer was I couldn’t find and xdf or bin files for the os anywhere else. I since found this forum and found the appropriate subreddit but still having trouble finding an xdf file since I don’t know which other models are compatible with said os. Any help is appreciated, now, back to digging.
