Well I don't blame ford really. The EPA is killing the 6.4 and now I keep reading about them shuting the delete programs down. I figure they can make ford do it with them putting out thousands of diesel trucks a day. But once the truck is purchased the EPA should take a hike. Hell Oklahoma doesn't even safty inspect anymore. You should see the beaters running around smoking. It has to be the dpf the truck is hardly pushing air out the tailpipe. Who knows anymore.
