i gaurantee you if he deleted it and put a cold air intake on it he would see an increase in fuel mileage before i put the basic mods on my truck and it had just a tuner each time i made a trip home i would have to stop about halfway through for fuel now i dont have to stop at all the entire trip for fuel and i didnt add an extra fuel tank or do the 38 gal rear fuel tank conversion nor did i change anything on the fuel injection system of my truck all i did was just help it breathe easier.

Us discussing fuel mileage hasnt commanded alot of my memory. Whole lotta shti going on here lately. No bueno.

I just go off what my dad has gotten. His 6.7s do better than his half ton with the 5.4. I do know that.

You'd be buying his parts if that is what you are "guaranteeing". Fuel mileage and flow rates dont overlap on a stock truck. If you think a truck trying to get mpgs is restricted by the stock intake and stock exhaust, you're confused. Those two items are only a hindrance if you are trying to increase power which has literally nothing to do with fuel economy.

Following your logic, 600hp 7.3s should get 30mpg.

The legit record for a 7.3 was just under 25. He was also the mod for the mpg subforum at that "other" site. Old hat. Nothing new.

Regardless of what the fuel mileage is (I was just hoping to keep the same mpg) I want bigger wheels and tires. I want to go 17's for wheels. Any recommendations on tire brands? Right now I have Toyos, they seem pretty good.

Look at the weight of the tires if you are trying to keep MPG's reasonable. The Toyo AT2 is the lightest/most aggressive tire I have found. I'm currently waiting on the 295/65R20s to come off backorder.

But I am wondering if Norfolk to Lawrenceburg is all down a very steep hill.
LOL

How long is this trip? I need some of that pixie dust if we are making it twice as far on a tank with just a tuner! What tuner?

Refresh my memory (it's been a long day already), what are we deleting on the 7.3?

I'd disagree that power has literally nothing to do with fuel economy... there is a fine line where power does impact fuel economy. Sure mopeds get great mileage, but there are also under-powered cars and SUVs that get crappy mileage compared to ones with more appropriate power levels. How about the difference in towing mpg with different power levels?


As far as increasing mpgs, the only thing that did that for me was small injector upgrade and tunes (about 1.5-2 mpg) which helped cancel out some of the losses from the lift, wheels, and tires. I was curious what the difference really was so I used to hand calculate and adjust for tire size since the odometer is off...

My X is mostly stock... intake/exhaust, set of 175/146 sticks, WW2, and tunes. Used to get 16-17. Now with lift, wheels and tires and we're at 14-15 uncorrected in town. CCSB full built motor truck (also lifted) gets 14 mpg uncorrected with similar driving in town so even heavily modded power levels didn't hurt the mpg that much (yes, I realize it is lighter than the X). Now if I drive the CCSB the way it was meant to be driven, MPGs are the last thing on my mind and it shows when I have to fill up LOL

Depends on what you want to spend and what you want out of the tire/what you use the truck for. There are plenty of tire threads, you'll find guys that like most of the big brands and completely different opinions on Toyos. Everything from 50k+ to junk and they won't last 20k. Honestly, if you have a tire you like, I'd stick with it until you have a reason to change or find something you really want to try.

Mopeds and cars arent what he asked about.

Having ran one truck lifted, unlifted, stock, and modified power levels I can say that in 260k miles nothing had the impact that a right foot did.

Anybody who wants to really delve into this, go to psn and read the mpg subforum. We beat this into the ground. Going from splits to singles may net 1mpg. May. Having kicked around the hypermiling forums as well its most definitely a right foot issue, fuel mileage. The guy getting the best mpg in a 7.3 was running stock ad's and a stock turbo. As well as stock intake and exhaust.

Your last post cfb, kinda proved what I was saying. In a heavily modded ccsb you tend to get the same mileage as you do in a stock, tuned, single shot vehicle of similar size and weight. One person who drives a certain way, gets the mileage that goes with that.

Yeah, yeah, I was just trying to illustrate the point that there is a small correlation between power levels and fuel mileage even if it doesn't really apply to this scenario... Blanket statements like that bother me when there is truth to it, just not for that particular scenario. That's one of the reasons I can't listen to right wing talk radio anymore, I think it was raising my blood pressure and I looked like a crazy person arguing with the radio... Sometimes I forget to hit my internal mute button LOL the worst part is I agree with a lot of their sentiments, but not the skewed arguments they were presenting.



Back on topic, I agree that control of your right foot is the best mod for mileage even if I did a poor job explaining.

I just dont like telling someone a 400 dollar intake is gonna give them 2mpg when it wont. Just lije it wont give them the 25hp the box says it will.

its not just the intake if you feed any engine more and colder it will perform more efficiently if you only upgrade the evrything that has to deal with air going into or out of the engine. by doing so you lean the engine out therefore it burns more fuel efficiently therefore getting better mpg down the highway. until you put a sky high lift and big tires on it or you increase the amount of fuel goin into the engine as well then your fuel mileage will either flatten out or decrease. diesels are more fuel efficient than gas engines because they're run by pure compression not compression and spark.

lol.. my dually went from 9-10 mpg with stock injectors to 14-15 mpg after injector and custom tunes.. same intake and exhaust... stock injectors had 60k on them.. way worn out with so many miles i guess..

You back on the hookers and blow? Sure you weren't fat fingering the calculator with that special math?




Lol those are some gains! I was happy with the mile and half or so I picked up.... maybe I need to trade mine in :D

according to Johnathan jones, ryan casserly rubbed his magic nut juice on them... and we are talkijg the same truck that track times put it at 470hp.. when it wasn't running right even.. it was labeled a freak back in 2010 while at beans shop...

and my brother drives like a lil old lady we added custom tunes from beans/dynoproven and he gained 2mpg across the board no matter what he was doing... same intake and exhaust

my 01 with generic ts tunes gained 2mpg across the board with same intake and exhaust...




and on a bone stock truck, about the only gain there is with doing intake and exhaust is that it should lower egts a hair while towing..

:doh: Not Cass's nut juice... You would be into that.

****** was known for 'special' dyno numbers... Although they've been getting better the last couple years. Maybe having a public dyno day twice a year has helped :shrug: (and toned down the adjustments). Practice makes perfect, right?

who said anything about dyno numbers? but since you mentioned it.. dynos are for tuning gains only imho, but it did do over 490 on beans back then..

Ill have to disagree, somewhat.

My 03 excursion, bone stock, 1500 miles, from Michigan to s florida, pulled 14 mpg.
While it was there, I swapped hpops, intake, exhaust, and tunes. Same route, same driver, pulled 18 mpg. And continues to today, 75/25% highway/two lane.
95/5% town/two lane still pulls 15-17 mpg, unless I'm driving, lol.
Yes, that's hand calculated.
