I'm thinking of getting my 170 remapped and to gain the full benefit I want to lose the dpf. As far as I'm aware out of main remap companies only custom code have a successful remap with dpf deletion. Has anyone had this remap? What are your thoughts? I'm going to speak to John at DNA who I've had do remaps for me before to see if has done this or can do it. But does anyone else know of a reputable remapping company who can do it?
