HELP---Should I buy a 6.4 08'?

[C6turbo88]

Need to make a decision tonight...

Looking to get back in the Powerstroke world, I use to have an 07 F250 Turbo Diesel, Found a 2008 with less than 20k miles for $32k. Just sold my GMC Sierra 6.0L Vortec because of the horrible MPG (getting 11.7 avg).

Upon my research, it sounds like 6.4L owners are not happy with their truck MPG. I don't expect to much, but I hope I can get over 17 MPG hwy and hopefully 14-15 avg.

I'm seeing people report from 10 to 18 MPG, seems like there's no consistency.

1. What should I expect on a 6.4 if I chip it with and exhaust with stock wheels?

2. What should I expect with a 6" lift and 37" tires?

Thanks

these trucks tuned with DPF delete can get great MPG, tons of power, and better reliability then stock. With stock wheels people are getting any where from 12-16 city and 16-18 highway or better. Now deleting the DPF will void your warranty if caught by Ford, but it might be worth the risk to get the results you want out of these trucks.

I'm sure others will chime in with more/better info. Just look around the site there's tons of good info.

Thanks, when you mean tune, are you referring to just a chip? Also, how do you delete the DPF?

Best ever stock has been 16mpg if I don't hit a regen cycle. Average about 13 mpg all highway. About 8 mpg towing 7k lbs.

MPG sucks DPF on, with DPF off i get 12.5 for city driving and 16 mpg highway.

love the truck otherwise

hmm not much difference from what I get with the dpf on. Mind you, my 35" tires don't help.

If your only reason to upgrade from the Chevy gasser, to the Ford 6.4 PSD is MPG's, then DON'T!!!

If you want to add a programmer and DPF delete because of any other reason other then MPG's, then do it, and a great side benefit is better MPG's. But if your are doing it for only MPG's, then save your money and buy 15 extra fill-ups.

But on the 16th fill up, you can translate that into savings. Keeps fuel out of the crankcase, and in the event you want to burn the tires off, you can.

+1 on that.

I havent seen where the tuned trucks with the dpf delete are getting much better mileage than a stock truck. Most of the posts I've seen are reporting 14-16 mpgs. As my engine is getting broke in, I'm seeing my mpgs go up. My last tank was 14.4 mpg hand calculated on 70/30 hwy/city mix (non-tow), and I'm completely stock. As stated earlier, if you want a power boost get the tuner, not for mpg's.
