Ok just came back from my second camping trip and averaged about 8.2 mpg on a 2008 f350 cc dually 4x4 KR with 88k. I was hualing a 25 foot lite TT with some camping gear in the bed. The truck ran like a champ but damn MPG sucked. Well I want to get my mpgs up there. So if I'm going to delete do I just do the DPF or should I do the cat as well. Keep in mind I will have to reinstall everything once a year for emissions. Who has the best price for a dpf pipe and dpf program delete. I don't really care for a performance program. I just want to get my dpf as cheap as possible.:look:

You can get away with just deleting the DPF unless your planning on making huge power and ripping your tires to shred, then I would suggest both. Removal of both will net you a little more then DPF alone, but you'll also end up with the infamous hair dryer sound as well.

If your expecting huge mileage numbers you will probably be sorely disappointed, especially while towing. Your best mileage will be unloaded and on the freeway. But no where near what others have posted sure to your gearing and wheel quantity unfortunately.

I'm not looking for more power. Maybe a little better mpg's. Wasn't sure if I should do both. Right now I'm looking at just doing the dpf pipe. Looking for a cheap tune to delete the dpf feature.

its easier to delete both. when you delete both, there are two bolts holding it to the down pipe, and one band clamp holding the dpf to the tailpipe. if you only deleted the dpf there are prolly 8-10 rusty bolts holding the two together thats a pain to get to the top ones with it still on the truck. if i were you i would look for a used h&s mini maxx or xrt PRO because it doesnt require sensors in the new exhaust. sct requires sensors in the exhaust and they tend to charge more for the bungs in the dpf delete pipe. spartan is more expensive plus if you buy new they charge a 100 dollar relicensing fee.

i went from averaging 9.8 mpg towing to about 12-13. not a huge improvement but enough to make me happy. i did an intake though too. i was hoping for 20 mpg like so many claimed but no luck. I once got 14.1 mpg but it must have been going down hill alot haha

I found a few dpf cat delete pipes with and without bungs. I was going to buy the one with the bungs. Just need to get a tuner to delete the dpf feature.

then find a used sct with some unlocks left, make sure its the off road version that is dpf delete capable. they are discontinued so somewhat hard to find. i think there are one or two for sale in the classified section. you will need to remove all the sensors from the dpf which is kinda a pain, and some buy extra ones so they dont have to swap them when going back to stock

the sensors going into the dpf. the h&s and spartan tuners dont need those sensors plugged in, but sct tuners need these sensors plugged in or the truck will idle at about 1200 rpms. they are just temp probes for the computer to know how its running, you wont lose any sensors that you will notice.

Dont do it for mileage because you will probably not get what you think you will. I just towed a 5x8 utility trailer 1200 miles or so and the best I got was 13.6 so I imagine if I had a decent sized trailer it would have been a lot worse.

Mileage depends a lot on how you drive. Mine went up from 13 mixed to just under 18 mixed. But I don't tow a thing and I drive very light on the throttle. I don't know how to explain Trav's numbers, they just are. Everyone's mileage is different based on how they drive and the trucks variance. Like a lot of people say, tune for power and mileage is an added bonus. Also delete both, its easier. Look thru the classifieds on here for deals, you can probably cut a ton off the price of the tune and delete by being patient and looking thru. Also diesels are getting better mileage on the higher HP tunes and keeping your foot out of the skinny pedal.

I just installed my dpf/cat delete pipe along with a h&s mini maxxmaxx yesterday and I agree do both I still have 9000 miles or July of next year on my warranty so it will be easier to put it back in as one piece (I practiced putting it back on lol ) so far my mpg has gone up a alitte but still early to tell did it more for the long run still fine tuning at this point

Can I leave in the temp probes if I use the mini maxx tuner. I would like to keep my egt sensor if possible. I would like to see an improved mpg but it's more for reliability. I here the dpf is a source for alot of 6.4 issues.

mini maxx.

Yes, you should order a delete pipe without bungs if you order a mini maxx.

I would go mini all the way. Also I know everyone gets different mpg buy here is my 2 cents. I went from getting 7.5mpg pulling my 26' tt I drive hard. And now since I deleted and installed an H&S the worst mpg I've gotten is 10 all hand calculated. I usually pull on the no power tune or mild. I belive you will see an increase in mpg pulling but don't expect more than 2 or 3 gain.
