I take my Work truck and modify it so that it gets better fuel economy it went from 10 mpg up to 16 mpg by removing carbon buildup in the intake manifold and removing the throttlebody plate from the butterfly valve in the intake manifold, this is going to be part one and it is especially focused towards all of the 6.7 power stroke owners that want to get better fuel economy and mileage and mpg. Although the basic principles in here should apply to every other diesel truck that’s 2008 or Newer and has an EGR and emissions system. Please make sure to like subscribe hit the notifications and comment on here then share it with any of your friends that are getting very very bad fuel economy other diesel truck..
