Just a K&N Cold Air Intake on my rig with EGR plugged in, I am seeing 13.7 City and 17 hwy. The 4.10 Gear don't help much for highway though I would stay away from that unless you are planning on doing a lot of heavy hauling. Im happy with it for being stock. I love the clean tailpipe absolutely no smell from the exhaust. I wanted a mega really bad but ended up with the quad cab only for the price. Whatever U decide on...ENJOY:thumbsup:

13 and 17 before deletes = Pussycat

16 and 20 after = Tiger

 

[-lenny-]

8-10 towing 15k 5er
10-12 city
14-15 hwy
All stock except for a cold air intake
EGR unplug did NOTHING for my truck. Your results may vary.
Smarty, DPF/EGR/Cooler delete, BOD intake to come, hopefully perk those number up.

By buddy did cold air intake, egr blocked and straight pipe including dpf delete, said he did get 16-17 city after that, changed his gears to 3.73 since he doesn't tow and picked up 3mpg.....thats what he says, he's not a bull $hitter but I find that hard to believe!

15 high way or city grand pa ing it flooring it. it doesnt matter with mine....

 

[gilbertmsg]

10-12 mpg towing about 5,000 lbs.

14-16 mpg mostly highway miles.

Best ever was 17.2 hand calculated (empty).

All better than my 04 Hemi that was traded for this truck.

after the cat, dpf and muffler fell off i got an average of 17-19.4 all highway on my way to ok hand calc during christmas. my lieometer shows an average of 15.8 right now all around town driving but i would have to say it is near 14. there was a noticable difference around town mileage with the dpf delete.

at least you can calculate how often you will need to fill up on road trips almost to a T!

 

[jakenok]

all stock, 2009 quad 2500 4x4; 2412 total miles, hand calculated combined mileage at 17.0 and going higher this tankful. I drive with the EB open always and usually in tow/haul also.

avg.

13.8 - city
16.2- hwy
11 - towing approx. 8k

 

[theotherhobbes]

I drove 4200 miles through 10 states from MS to NV and back during Thanksgiving. I averaged 17.2 for the trip (hand calc'd). Lots of 75-80 on interstate and a good bit of low speed looking at the grand canyon, painted desert, etc.
Towing about 15k = 10-12
Avg mixed driving is 15.5-16.5. About 70% highway.
If i baby it with the cruise set on 60 I can get 19-20....About 12k on the odometer so far.

 

[sofakingbad]

my first tank i got 12.7 mpg. im working on my second tank now

 

[Cummin'Not Stokin']

Whoa! Sofakingbad, Are you really trying to sell your 4th gen Goodness, Payments getting a little steep on her?

 

[4NEATR]

i don't remember what the truck was getting for the 4 hours that it was stock. :rof but i have about 105000km (62000m) on it now and on the hwy i get about 1100km (685miles) per 7/8 of a tank averaging 70mph, i drive lots of hwy for work. That is with the xrt on 60h and the meth shut off.

 

[cabanaman]

mpg

6.7 with k & k air filter. 10-12 in town. 12-17 hwy depends on speed. 39,000 no problems but only 8-10 pulling fifth wheel. I got these same mpg on a 1968 ford truck F250 camper special. i had it 12 years and wish I had kept it. buy a 5.9 if you are looking for mpg and pulling. these 6.7 lost their mileage when Oxygen sensors were replaced. I had a 1980 Dodge Colt hatchback that got 44 mpg on road and had a "factory required check" and it dropped to 20 mpg on road. oil companies were with auto companies in those days. sold it after 3 years.wish I had bought a gas burner. It will get the same mpg and save thousands on motor and fuel.

Yea , I wish you would have kept it too....

:agree2: If you don't want to do what it takes to wake up your 6.7's mpgs and stop the soot from ruining it then get rid of it. You can do a minimal delete for $200 and be able to return it to stock in a couple hours. No excuses:banghead:
