Well I am happy to say that there should be another tuner available for the 6.4 here soon. Superchips picked my 2014 6.4 hemi up from my house today and will be using it as their test truck. This is the second time I have done this for them. I am super excited to get my truck back even though I am deployed and won't be able to drive it until I get home in a few months. However my wife will get to tell me how much more fun it will be. So moral of the story is if your looking for a tuner wait a few weeks and see what Superchips has to offer!!
