Im putting a Smarty S67 with the ME software on my cousins 12'. We have the deletes ordered but they haven't came in yet. My question is, is there an option on the screen when programming it where you can choose to not delete the dpf and egr? Of course we will retune it when the deletes come in and we get them installed. He is just dying to put that smarty on it and I don't want him to drive all the way to my house just to figure out that its not gonna work until we get the deletes installed. Thanks
