So I took my truck in this morning for a CEL. After my truck was finished I talked to the diesel tech. He told me if I had a 5.9 then he would not care one bit if I had an Edge as long as it were off when it got there, but he said no way to the Edge on the 6.7. Then he tried to convince me to trade my 6.7 for a 5.9. I still want the Edge:thumbsup
