i did dpf delete and smarty around 3000 miles, got very little, then around 6500 did a downpipe swap, got a couple of mpg, then at 15000 it came alive, now at 32000 with the right tune i see around 22-23 on the hiway, and i have 4.10's

 

What's your over all economy? I've had a best of 20.5mpg hand calculated. My typical mpg is 16-18mpg combined.

I've seen my "overhead" at up to 25-26 mpg when driving at 55-60 on rural roads for 20-30 miles at a time. I know the OVH is not correct but it normally has a inaccuracy of 1.1 mpg, I do believe I was getting an honest 24 or 25 mpg when driving like that.

 

Here is my truck:

2009 Quad cab 4x4 short bed with 6.7 and 6-speed auto 3.73's....

I have full 5-inch exhaust, Diablosport programmer and Air Raid Cold air intake.....on trips of 300+ miles I see an average of 24-mpg...

Piss on the warranty......I needed the fuel economy!

 

24mpgs seems high, are you going off the OH, or is that hand cal.
cause i am only getting around 19-20 but i have a smarty and g56.

I just looked at your sig. and it says that your truck is 2wd but in your post you say is it 4x4 so what is it going to be?

 

I always refuel when down to a 1/4 tank. So hand calculated with mixed driving I went from a range of 13-19 to 17-21. Big improvement I'd say.

 

Stock I had a high of 21.5 MPG US
After Deletes a high of 25.5 MPG US
Average 22 MPG US
with 245,000 Miles on the clock one quarter of my goal of 1,000,000 miles

I think that you'll find different figures with this question but I think the general rule is after you do the deletes your mileage will improve. I even read on here somewhere where a guy went and drove a bunch of new cummins on a lot and got a different reading on the overhead in each truck driving the same way and going the same route. Me personally I just tightened the last band clamp on my 5" maybe an hour ago. After driving around town the overhead jumped up almost 7 mpg is that going to show up when I do the hand calculated tank later on this weekend? I hope so. Even if I only get 1 more mpg I don't care the truck is a beast now and I am so happy with it! Its night and day difference IMO.

i would like to get better mpg but have a good sound and let people know your commin is what i really want.

 

when in regen you loose a lot of mpg. Nonsense...... No regen, better mileage. I went from 18 and 14 up and down to 19 to 21 constant.

 

Just did mine 2 days ago...I was getting like 15-17...just got 21.5 all the way from my girlfriends back to my house...its about 1/4 highway, 2/4 two-way winding road, 1/4 smaller backroads.

 

I went instantly from 19MPG to 21MPG with my mixed commute, all hand calculated. This is with a turbo back exhaust and a Smarty on #2 (stock timing).

 

i went from 13-16 stock to 17-23

 

Just put a full tank through her since the deletes (11,500 miles on the clock)... I got the G-56 with 3.42s (stock tires) with 5" pipe, no muffler and smarty on 60hp with default settings (stock clutch)

About 75% highway 25% city to include a 40 mile trip with Oak logs in the back (filled).

Got 575miles with less than a 1/4 tank left, and 30 gallons.

Hand calculated 19.1 MPG

Before deletes I was getting ~17MPG

 

On a 500 mile round trip (90% highway) I got 18mpg stock and 24 mpg after deletes with XRT on 120.

 

On average people are seeing a 3-5 mpg increase. These numbers can applied to any over inflated original mpg calculation.

Now, one of the best improvements in mpg's comes with miles. 50000-70000 seems to be where most of these diesel trucks reach their mileage sweet spot. IMO

 

Hey Alverado 6.7...I just bought a New Legend 40-foot Gooseneck trailer in Alverado, TX on Saturday, very pretty country!

My truck has no lift, and stock 265 series tires....no ranch hands just a gooseneck hitch in the bed.

I buy my fuel on a credit card so every month it spits out my bill with ACTUAL FUEL USAGE...and those numbers do not lie!

 

Thanks I like it here myself too.

I was not directly singling you out in that comment. It was meant to be a joke to everyone. Sorry you took it that way.......

I'd have to get to know ya better before I start questioning your integrity. rofrof

Enjoy your new trailer!!!!

 

You have to remember I am a Ford guy at heart and have a few fords too...

The guys on the ford forum like to talk $hit all the time when it comes to mileage..........so i tell them that any mileage I get in my Dodge's or Ford's can be backed up on paper.........

It is cool...I didn't take it to any defense

But where you live is sure pretty country!

Thank you sir for the kind words about my neck of the woods.

 

you know of anyone with any 22.5 or cut down 22's for a Dodge? I lust bought a 2010 Ram 3500 Long Bed crew cab 2wd truck a few weeks back. It is in the shop for a shifting issue with the 6-speed manual but when it gets out I would like to do the big rig look.......I found a set on craigstlist in ft. worth when i was in town but the guy would not answer his phone.

I put black KMC's on my truck the day I picked it up and since then I wished I would have splurged for the bigger ones.

If you come across something that might work give me a hollar.

Thanks

Aaron

 

Will do. Check the classifieds on here. That's where I found mine.

Also, I would stick with a 22.5 and not a shaved 22
You'll have better tire options for the 22.5's if you're looking for a high mileage tire. IMHO


Sorry OP, thread hijack is over.

 

I had my Dodge done about 2 month ago, I average driving hard 17.5mpg in town and towing my boat around 16mpg but on the Hwy I average between 19-25mpg depends if I drive hard or not. Before I was getting between 12 and 14 mpg huge improvement!

 

Sorry about the hijack!
