Question Questions about my 6.4L

I have a 2008 F250. It is stock right now and has 39K miles. Im only getting 12mpg. I want to improve my mpg and was wondering what would be the best/safest way. I want to get a DPF delete and wanted to know if it would cause any problems, make any caution lights come on, or avoid warranty? Thanks for all the help

Do a DPF delete with a tuner.

do a delete and tune it. it will run great and improve mpg and be a lot faster. you cant be covered under warranty with a tune and dpf removed so you will have to take it back to stock when you go to dealerships.

yupp, i would just do a delete pipe and a tuner so if you need to go in for warranty you can swap it back on!, check out your options with tuners and " not being able to be picked up by dealerships" most people on here go spartan or h&s, but edge and others make nice tuners too.

Go with an H&S or Spartan tuner for the best results. Pair that with a Flo-Pro or AFE exhaust kit and you have an excellent package. Feel free to give me a holler with any questions.

theres a few good ones out there, but my opinion would be to go with spartan or H&S. i may be a little bias but i say spartn. the power gains are just insane and they are the least detectable by dealerships. i may or may not have returned mine back to stock, taken it to the dealership and had three computers hooked up, and not been detected. and when you decide to get one, i would 100% by from nate at performance truck products. hes a straight shooting guy and will give you the best deal you will find and top notch customer service!f whenever i need another mod i will be going back to him!

I'd say for fuel mileage choose sct with IDP tunes.. A dashdaq w/ erics tunes would be the perfect setup

I had tried two different dealerships last week since I had a 5k service coming up. Both said, you do anything, we'll find a way to void just about any warranty work. Decide to just get an appointment at one closet to my work. During the appointment scheduling, the assistant service manager told me if I bring it to them for all scheduled maintenance and warranty work, they won't say a word. Just put the CAT/DPF back on before coming in and leave the intake on. Needless to say I was so happy, I ordered my stuff. He told me there was only one instance where they could not cover an issue associated to an aftermarket part. The guy soaked the filter too much and basically shorted the mass air sensor. They ate the labor, guy had to buy the sensor. While he did not state specifically, ford might be providing incentives to dealers for finding faults that will void the warranty on these 6.4L. Check around, you will find a dealer that is interested in servicing your vehicle to keep you coming back...

thats awesome. im really surprised he came out and said that. most of them do what they first told you. the one time i had to take it in, i was asked 5 times in about 3 minutes if i had a tuner on it. when i told them no, they said if i did they would find it. the only dealership i've heard say they will work on it even though its modded is one up in the panhandle in a really small town. they said if they were slow, they didnt care if you had nos on it, they would still work on it.
