I have been getting 17city/21highway around the hills of Ky. I have 119000 miles on mine now, it seems to just be getting broke in. I have a cold air intake, downpipe back 4 inch stainless steel straight pipe, with an SCT Livewire programmer. I get 14 to 15mpg towing a 10,000lb trailer. It seems like it took forever for it to ever get that kind of mileage though. You can check my older posts, I've tried to keep up with it since I bought it new. I have posted everthing I have done. Hope this helps. I don't remember what it costed for sure, I think it was around $1100 for the pipe and programmer.

Thanks for the reply. My problem now is that i live in Ca. and we have to smog our diesel trucks every 2 years or so and I would fail the visual inspection right away if I did the cat/dpf delete setup... I now have a cold air intake and an aftermarket AERO TURBINE muffler and that's supposed to help. I'm real skeptical about chips and programmers when it comes to my warranty. Any suggestions would be great...

I had a Superchips Cortex programmer on it before I took off the DPF and Catalytic Converter. It improved the performance but I don't remember the miles per gallon. I don't think it will void your warranty as long as you set it back to stock before you take it to the dealer

I have a 08 250 with the 5.4 motor. this truck can't get out of its own way. The gas milage I get is 8.1 when 4x4 is not being used. It cant move on ine or mud without 4x4, but this may be the factory tires. I had to get a front alignment and Ford replaced two tires. Last inspection I could not turn the front wheels, upon closer look the brakes were rusted in the slides so I removed them and wire wheeled lubed and assembled. The dealer said it is a problem in northern climates. I have owned Ford for 25 years, but am considering another brand.

#400 of 401 Turbo Booster and Particulate filter by notlovinmyford

Our 2008 F-250 super duty 4x4 has been having very expensive issues and I'm afraid that they will continue. We just had to replace the turbo booster and the Particulate filter was taken off instead of replacing it, but now it runs really rich. I was wondering if anyone else with this model year was having these particular problems. I really feel it is an issue that Ford shoud address, and if there are enough of us with problems with the 08, maybe we can band together and get them to listen.
