Default 155cc or 175cc injectors

Here's some back ground on my 2003 Souper Doody: 104K, OEM head gaskets/bolts, new oil cooler/coolant filter, blue Spring, SCT with SRL as DD, 3.5" down pipe/4.0" straight pipe, "home made CAI", ~4" lift w/35" BFGs and 3.73s, Pro Comp traction bars, rebuilt 5R110 with shift kit (thanks Edge!), 2004 intake manifold, Banks Techni-Cooler.

I was looking over injectors and I have a few questions:

Are the MPG increase claims true or a smoke screen to get you in?

Considering I want to keep my turbo, would 155cc injectors be a better choice?

Is it going to smoke like a freight train with larger injectors? (I would get an injector tune to match.)

The fact is, my truck makes plenty of power for me as it sits. From this point, the only other bolt-ons will be for MPG increases. Let's face it, 13~14 mpg in town at 4000 ft isn't that bad, but it could always be better. Or should I look into an MTW hybrid to make up for the thin air here?

Given the big bucks for injectors, would I be better off just getting a set of 4.10 gears to correct the speedo/shifting? I mean, I have seen guys put 35s on a gasser, get *** mileage, re-gear and get that mpg back.

Thanks, Karl

Honestly Karl, I'd have a real hard time buying injectors based on the fact you're trying to get MPG. Will you get some? Maybe... but how many gallons of fuel can you buy for the cost of injectors? It would likely take a long time to make that money back, IF you even got any better mileage. If you want better mileage, you know exactly what you have to do, put the truck back down to stock height brother. I don't see gearing helping you out either honestly, unless you do ALL city driving. I gained mileage going to my 35's because it lowered the cruising RPM and I live at 75mph.

I'd think if you were going to step up injector size, you'd likely want to at least do a MTW stage 1 or a hybrid to match. Going big on the injector is ok, but if you don't ever plan to add the air to match, the tuner is just going to pull fuel out of your tunes, which is counter intuitive to getting injectors in the first place.

At least that's my 2 cents.

Id do gears first. Would think it would give you better mpg being easier to turn those tires.

95% of my driving is that dull 10/12 mile drive to the hangar. Occasionally we go 65 miles to Reno (but it's easier to park her 07 GT in Reno than my F250) and ONCE a year we do the "Over the river and through the desert to Grandmother's house we go".

Given that, what diff is in the front of the 2003? Dana 50 or Dana 60? My mud truck axle actually says D60 on it.

I believe they're all D60's, but I think the 05's just got a beefier D60.

Yeah that might be right Curry. Some fancy terminology like that... My understanding was that before those, a CC/LB dually wasn't technically able to have a plow hanging on the front end, as it was over the weight rating for the front axles, but with that new axle it was acceptable. Even though, guys did it anyways.

The Super 60 was on the DRW trucks.

Gears will only make the RPMs higher, to me that means more motor, less fuel. Gears do help when tires exceed a certain size. For 35's stock 3.73s are fine. I get 16+ with a 6" lift and 35's.

I'd recommend some FICM tuning first...at least it's cheaper.

Default fuel econ at stock

05/6.0
im wanting a better fuel econ too.......these prices suck a**.....so as im reading im seeing that doing a ficm readjust is prob. the best thing to do? so if this is true do i at least want to do a exhaust upgrade to 5" to rid of the extra heat from doing a 58 volt up grade and then maybe a tuner?????????..........
