SEMA's website is showing the Kook's headers for the 6.4 and says that they do not need tuning with the green catted ones. Also JET had a performance module for the 3.6L Jeep. So I wonder if JET is the one that is gonna have tuning from MOPAR and Diablo happens to have broken the code at the same time?

That would make sense since Joel on the red site said it would not be a handheld, all jet does is chips so...
