The PCM flash is only for the 7.3L trucks. For the 6.0L trucks we use the SCT programmers and I suggest either my 40hp tow/brake or 60hp tow/brake for the trailers depending on the weight and my 80hp daily for empty driving. https://www.dp-tuner.com/x4-7015-6-0l or the touchscreen https://www.dp-tuner.com/livewire-ts
