I did all the deletes. Did Sinister EGR and EGR throttle and cooler delete and full 5" turbo back exhaust by Flo Pro and EFI by Ryan tuner and Injen cold air intake and my top mpg so far is 26.4. I'm taking trip to NY soon and hope I can hit 27mpg. Also I'm new and it's funny to me to put it on tune #3 and do a donut in a dually lol

You need to hand calculate, those numbers off the overhead are not accurate.

I'll try that on my trip to NY. Plus it was better than the 16.7 I was getting before all the upgrades.

I just got EFI by Anarchy. I don't expect any improvement in mpg. The truck's just so fun to drive now and with $2.00/gallon diesel who gives a s***.

You should see around 21-22mpg in ideal conditions. WHen I first deleted my truck it was like a whole new animal. Loved it. Still love it after 60k+ miles. Totally trouble free.

I would love to get anything like 20+. My overhead shows 18/19 and my hand calcs are always about 2 less (getting 17/18)... Which is still way better than the 13/14 before deletes...

I just went to Pensacola, Florida and back and ran Diesel fuel injector cleaner and octane boost in same bottle. I averaged 27.5 on the overhead and hit a high of 29.1mpg. I'm happy as can be. I spent $300,00 total for round trip in gas.

As Lary mentioned, those "overheads" are inaccurate. Some manufacturers have been sued by the US Govt for purposely altering the readings generated there. Toyota, for example.

You need to fill the truck to the brim, drive a long drive, resetting the trip meter for miles, then fill it up at the end of the trip. Divide the miles by the number of gallons you filled it up the second time.

My wife has a sequoia, and it reads 3 to 4 MPG better than I'm actually getting doing the manual calculations.

Still only cost me $300.00 in Diesel Fuel round trip to drive 2k miles.

DIESEL, not gas

There are lots of inflated claims of 'far-out' mpg #ers... THAT is why we arn't taking the hook. Prove it and we will take it.
Cheers friend! I'm not out to get you. Just want straight talk, hard facts.

Welcome to the forum!

Okay, NOW tell us how many gallons of fuel and exactly how many miles. then we can dope out what you really get for MPG.

Guestimate:

2000 mi at $2.5 gal is 2000 /(300/2.5) = 2000/120 = 16.6 mpg

2000 mi at $2 gal is 2000 /(300/2) = 2000/150 = 13.3

The tank is 34 gallons. I filled up twice. Once when I left Florida and Once at bottom of Kentucky when I took a pee brake. I also don't have 4 wheel drive. Mine is only rear wheel drive dually. Sounds like a bunch of Hater's . If the overhead is 2-3 mpg off and I reached 29.1 then at the best I still hit 26. I used $180.00 in Diesel on the way down because I got stuck in traffic for 3 hours cus a semi turned over on 75 and I took a nap because I was tired. I only used $120.00 in gas on the way back home. So weather you guys believe me or not doesn't matter to me because I know what I spent and I know how far I drove. It was 990 miles one way and 990 mile back home.

Not a bunch of haters, just owners with a realistic view. Yes there are trucks that are anomalies and get better mileage than the average truck but they're few and far between.

As stated above, (sorry for the long winded version)
For a road trip the correct way to calculate mileage is to fill it up before you leave so you start with a full tank. You keep track of all your fill ups and mileage while on the trip and fill it up again when you get home. You divide the total mileage by the total amount of gallons purchased on the road and to refill at home (don't include the initial pre trip fill up) and that gives you your mileage.

If you didn't refill the tank when you got home then you're missing alot of gallons for the hand calculation.

Or you can continue to believe the lie-O-meter and we'll reply to a post from you in the future regarding a "drastic loss of mileage and what do we think the cause is"...

Really, I hope you got great mileage but I think you're missing the refill gallons.

My O/H without programmer is 3-4mpg off, when I had my Quad on it was 7-8mpg off. As the poster above me said, I believe you are forgetting the final top off in your equation. Right now mine says 19mpg, I'm getting 15.5mpg 136K miles that's without a programmer to make it even more off.

Before my lift my truck was one of those odd ones that got great mileage, I consistently was 17+ commuting in the SF bay area, I hit 20+ twice once going to Reno/Tahoe and back the other was to Monterey. On trips I could easily get 19mpg, but it was darn hard to hit 20mpg. I couldn't do anything to hit 21mpg, and keep in mind I am a good fuel economy achiever. My 08 Patriot was rated 29hwy, I never saw below 32mpg including commuting 32K miles, my wife's Prius is 51hwy, I get 55-60 with a couple of 64-65 trips 22K miles. My bike is rated at 71hwy, lane sharing in stopped traffic I get 68-69 depending on how much I fart around at 7000rpm's 4K miles. I haven't had a chance to try highway speeds for long enough distance to compute. Look at my sig, those are lifetime fuel economy, not best achieved.
