I don't want to hear about your MPG's
thanks in advance for taking the time to read this post.
I know I'm asking for free advice, so maybe I shouldn't have the highest expectations. I have spent the past couple days reading posts about MPG's on this forum and have really gained nothing but frustration.
I know most problems are probably these simple fixes:
Winter blend fuel
Turbo leaks exhaust or clean air side
I get it
Also others who have asked often get post of guys who jump on and comment about their 12 thousand pound rigs with 40 inch tires that are getting 29 MPG.
Please don't tell me your MPG and don't relist any of the obvious solutions.
Sorry if that sounds rude- just trying to get some good advice.
My truck is a 2001 F-250 Crew Cab with the 7.3. I have a new stock air filter, new fuel filter, Good fuel pressure, no codes, good boost, 31 inch tires, number 2 diesel fuel, a clean EBP, a 4" turbo back exhaust. I cannot seem to get better than 12 MPG, and I drive like a 150 year old lady. The truck just passed an injector buzz test, and a cylinder contribution test. It has just over 200000 miles on it. Injectors are probably originals.
Runs good no smoke at all, ever.
Where do I go from here?
One far fetched idea I had.... If the previous owner had a programmer and then pulled it out of the truck when he sold it to me, could it have messed with my pcm's programming?
Any other ideas?
