It should. It worked on the 6.4ls. I don't see why not unless the ha tunes are locked.

Make sure your tuner isn't changing your OS or vin numbers. I know someone with a 6.4 who's SCT changed the OS number. He licensed the deleted reads but the stock read wasn't licensed.

So what do I need to do if I get a checksum invalid on a different OS that is a deleted read? can I email support and get them to fix the checksums so I can license that read and flash my changes Random Enthusiast?

As long as it's a stock vin it licenses by vin number I believe. I haven't done anything with the 6.7's so I can't say for sure. But it worked with 6.0l's and 6.4l's.
