plug the tuner in without loading those two files in, go into the diagnostics menu and select show calid it should bring up a number for the pcm and if working the tcm. Eat your tuner back to stock after that and run load a basic tube for each file, that should save an original backup file for both tcm and pcm. Go through the advanced load options like he said to do to load both files. The custom pcm tune gets matched with the original backup for the pcm the same goes for the tcm ( easiest way to make sure theseare separate Iis to put the originals in a different file than any new tunes you receive, thus way you don't mix them up). After they get loaded, take the tuner to your truck but before you plug it in, turn the key to the on position ( not started) then plug it in. There have been issues with loading the tunes in the 05 & 06 years. After that load them up and see what happens. I could not get Sean's tcm tune to load. not sure if it wasn't written right or what but I went else where and am thrilled with the results. Another thing to ask that I am not sure would or would not make a difference is to make sure he knows yours is a 4.7 not a hemi, the file might have to be different, again not sure on that but it's worth asking. If you still can't get it to work I'll give you the name/ number of the guy that did mine and you can see if his works.
