I think my truck is addicted to fuel. I get 10 mpg pulling two four wheelers, I also pull a 32ft montana, not at the same time. Pulling the rv is alot worse. My father and brother have dodges. And I really get hear about it When they are waiting for me to fuel all the time. It blows alot of black smoke. My bumper is stained black. My edge shows high egts once even 1500. Ive changed fuel filters, had my injectors tested, my pulse readings are in spec. I have been running lucas in the fuel. I even talked to edge tech. The engine dont miss idles perfect. I havnt did the egr block off and the pvc reroute yet. I didnt know about that until reading from this site. my truck only has 64k on it. Plus I only get 12 pulling nothing. If it helps its an auto 6 speed. Thank you!
