EZ on 600
Don't do it! The EZ is not yet available for the 04. 5 Cummins and even though it will plug in after some time it will cause the fuel pressure regulator to overheat and the truck will miss or stumble. With continued operation the truck will stop running and the regulator will need to be replaced. I have spoken with Edge about htis and the word is that they will be releasing the Juice for the 04. 5 before the EZ. So you may need to wait awhile for a box.
