So my plan was to but the DTLT and the X-1 at the same time. My question is if I have the X-1 will i need the o2 sim? also will it hurt the truck in any way if i dont have the x-1 or the o2 sim with the DTLT installed? I have read that the check engine light will stay on but is that all that will happen? I really wish the x-1 wash in stock because i have the funds lol.
