2008 F-250 6.4 with 200K for towing

[fletch0467]

I was just looking for info. just bought 2008 F-250 with 213K miles, all stock. We are using it for pulling our 30Ft Travel Trailer 9,700Lb. What mods would give me the best MPG's? running CA to PA and Fla. We live in Hinkley California( smog every 2 years). Any info on this would be GREAT ...Thank You

Personally, I would not have a factory DPF equipped truck in a state that did smog inspections unless you were willing to put it back every two years (or find an understanding inspection station). The DPF is easy enough to take off/ put back on, but the EGR system isn't. I really like the 6.4, but I wouldn't own one and leave the DPF/ EGR installed. My advice, look for a different truck. If I lived in CA, I would buy a 94- 98 12V Cummins.

this is not an educated post as i am very new to all of this, but i just did an s&b cold air, diamond eye dpf/doc delete, and a spartan tuner and i really have to say that is the best feeling driving that truck. it really has made it smooth and sounds great. it is now the truck i thought it should be. it does not feel like it works at all when accelarating and you can just feel how efficient everything is now. i have not figured out my mpg but my mpg meter was 8 when i drove to the shop and 17 on the same route home. i don't know what they will say with 213k on the clock but i'm pretty sure it is going to get into another h&s or spartan debate!!

If you live in Cali I'd move. No joke I'll be dam*ed of I'll live somewhere that takes my freedoms away. Anyway dpf delete and h&s if you don't remove the dpf your just asking for problems

I AGREE WITH THE MOVE PART 1000000000%

There are alot of good people in cali paying the price. Its a shame good luck with the truck tho.

Thanks for all the info....DPF and Cat delete, cold air intake with a tuner for sure...just have to do what i gotta do come smog time...

You'll never regret it man I got my h&s mini maxx and 5"flo-pro downpipe back exhaust for 1200 best decision I've ever made.

If you are going to do a dpf/cat delete and keep it registered in CA then I sure wouldnt spend the money for a full exhaust system. I'd get just the delete pipe to put into the stock exhaust system. That way it will be much easier to swap in/ out for smog inspection and will look stock to anyone that it may concern in CA. For an intake I'd make sure to get one that's CARB approved so you won't have to put it back to stock. I wouldn't do an egr delete either since it's more work than its worth in my opinion if you were going to go on and off with it. My first decision would be register that thing in a different state.
