I have a friend with a 08' 6.7 CTD and he is looking to some exhaust and program mods. He has been having some local guys saying that he needed to install a fuel rail plug to increase his fuel pressure. He asked me and I had no idea what to tell him beings my truck isn't a CR system. Any info would be great.
