Along the same topic here...
I am going to purchase a programmer from a guy that had customs tunes in it for his 2008 F150 5.4L. Can I run those tunes on my 2006 F150 5.4L? If not, can I just put it back to stock even if I am not the original owner?
If I have to change the tunes, do I have to send it in....or can the new tunes be downloaded?
