I have a 2016 F250 with a 6.7 diesel, 6 speed automatic. Has anyone tried putting a chip in one of these trucks to get better MPG and do you think it would harm the truck? Thanks, Happy Camping
Not to mention a large percentage of warranty work is because of emmisions stuff failing or causing excessive wear/heat on other engine components. Factory programming is based heavily on making your truck quiet and clean. If you care less about those than the factory, you can improve fuel mileage. It isn't a huge a gain as some people claim, but it is real.
