the lift and 35" tires probably aren't helping your cause to much, do you have the speedometer corrected for tire size?

 

YES IT IS CALIBRATED AND CONFIRMED BY MY GPS AS TO SPEED. WHAT TUNER DO YOU USE? I AM THINKING COLD AIR INTAKE MAY HELP, BUT IM A DRIVER NOT A MECHANIC AND THEY ALL OF COURSE CAN PROVE THEY ARE THE BEST, ANY TIPS?

OH P.S. - Bought truck in feb 09 i think and 41k mileage so do i really care about 3/36 warranty.

 

delete your DPF and you will see a huge difference in MPG

 

You don't are about the 5/100 diesel engine warranty?

 

Man I sure wish that I knew this before I deleted mine!

 

I don't know if GM runs their warranty the same way...might be something worth looking into if you can.

 

So far all i've done to my 6.4 is add a AFE PRO 7 DRY drop-in air-filter, I'm only getting 12 MPG in the city & 15.8 MPG in the highway. I'm at 14,692 miles

 

I am sure being of a high caliper intelect such as yourself, you get TONS of bs questions regarding the Fords Diesel. Well sir here goes another ( if you dont mind). I purchased my first Diesel back in May, I have always been a gaser kinda fella, well I am finding that she is like a wife very expensive to maintain and heck to any upgrades to her for that matter.

I want to do some upgrading but nothing that is going to void the warranty ( at least until it expires ( almost 57K miles on her now ) fuel MPG is killing me @ 10.2 10.4 in town, and maybe 13.5 highway. Would you happen to have any recommendations for me that are fairly cheap ( i blew my wad on the truck buying it and the wife, well im sure you know! ) and a good quality product.

Thank You sir for your time and patience
I hope with your reponse I am able to do the upgrades and report back with positive news.

Thanks again

From what I have seen and read the only way to get any reasonable mileage gain is to delete the DPF.

 

everybody that buys a dpf delete off of me reports back good mpgs.
