Don't buy this Flashpaq 1858 tuner, as I made that mistake. My 6.7L is sitting at the dealer after 8 days, and somehow the tuner left behind ghost data that Ford Detroit Engineers knew it was Superchips. I now have a voided warranty, and paying $5000 out of pocket for a new catlytic converter and new DPF. They said the PCM had corrupted data, that the DPF was allowed to get extremely hot and incinerated the internal parts of the DPF. I had to be towed.
