Can I ask why you're not having the dealer repair it on a 2014?

he says its a corrupt tune and needs to reflash (old terminalogy)the TCM ,,,,,,he panicking now and doesnt understand what hes asking or reiterating what he was told by his "tune " guy

 

and i use the "tune guy" term loosely

 

this all makes no sense

 

have a good day folks lol

Because A.) it would not be under warranty since his truck is tuned and B.) his tuner flash locked the tune and when they do that no one can communicate with the computers and re-flash them at that point. Either going to take have the tuner/tune company to unlock it or else replace the TCM and flash it back to stock calibration which is going to be $$$.
