A guy has asked me to put his truck to stock, he's not sure who tuned his truck before but he doesn't like it. It's a 2010 4.8 4 Speed
Engine Operating System 12636005
Transmission Operating System 24243357
Stock Tune Files doesn't seem to be working... If anyone here could help me out or point me in the right direction that would be great!
Here are the files I'm working with.
Thanks.
