Boys I know there is nothing like a delete diesel, of any kind. I have two 6.7 cummins delete (bad ass) one 2013 cummins non delete (terrible fuel control), but also have a 2014 ford 6.7 stock.It is the best controlled system I've ever seen. Good fuel delivery, good shifting and stupid pulling. This truck has a 3.31 ratio and will out pull my 2013 cummins and gets better fuel milage by far, especially loaded. Plus it has a lifetime power train warranty. I believe Ford figured it out.
