SCT is the most common and popular tuner for a 6.0L because of it's ability to hold custom tunes. We, along with pretty much all other tuners can write custom tune files for them. We also offer the Infinity which is a Ford enhanced monitor, datalogger, scan tool, and programmer that can hold our custom tunes. It is similar in function to the Livewire, just more advanced with more options. You can check it out
HERE if you would like.
Feel free to ask me any questions you may have. I'll gladly help you out.
