I know the 6.0 is not a economy based engine, but... do the tuners or chips give you any noticeable change when driving at a normal speed on long trips? I can buy a chip relatively cheap and they advertise better economy but I would like to hear this from others who have tried it. This engine has been out for so long there should be plenty of proof out there. Any input is much appreciated.
