Chipping F-350 7.3L Godzilla
Hello: Looking for anyone's experience chipping the 7.3L Godzilla? Truck is 90% used for work, looking to improve the economics of driving. Some chip manufacturers are claiming 2-3MPG improvement with no tattle tell signature to void warranty.

I guarantee that if Ford looks deep enough they will be able to tell if it's been tuned. Whether they will or not no one really knows. It always seem like the economy tunes just change throttle mapping so maybe try changing driving habits first? Or run in eco mode all the time.

super duties are not yet rated by epa as part of corporate average, but the end user cares. The market takes care of it just fine and in fact is more efficient than an arbitrary standard because the fleet operators care about a combination of reliability, economy, and usability.

"Chipping"???
Nobody does chips anymore.
For what you are actually talking about, pcm tuning, most times you will download the new tune with a hand held interface device.
And, the fact that the pcm has had a new tune downloaded is very easily traced by the tech at the dealer when he plugs his scan tool in and scans the pcm.
This, of course, will give Ford the reason to void the warranty.

Ford had plenty of incentive to make the most powerful gas engine around, and that includes making it a more efficient air pump. The days of a chip, cold air intake, or exhaust doing anything other than emptying your wallet are long gone with naturally aspirated engines.

Tuners can restore the factory settings. I don't believe the dealer could tell if it had previously had a tune.
TFL truck did a review on the 5 star tune. Looks pretty good! With rear wheel dyno numbers too.

The ECM logs all reflashes, so it's easy for a dealer to find our if an aftermarket tune was installed, even if it was later replaced with a stock tune. I am told that some in-line devices like Pedal Command don't leave any evidence of being installed, buy they don't do much.

And, yes, any device that intercepts the signal between the engine and pcm but does not reflash the pcm would not be detectable, but those devices are extremely limited in what they can do, nothing like what a full tune would do.

There's stuff you can do.
1. Keep your foot out of it, run Eco mode.
2. Higher PSI in tires. I just went from 60/70 to 65/75 today. Now that the tires have 4000 miles on them the ride should be OK.
3. Get a tonneau cover. Keeps you stuff out of sight and dry.
4. Unload stuff you don't really need

This is a unique place where…slipper wearing camper owners and people that work out of vehicles collide. 😂
“chip” it I say, but, you take a chance of warranty denial. You can get a lot better mpg out of all engines when the epa is ignored.

Been driving a 2004 F350 with the V10 since 2005. I've tried to baby it for the best MPGs which is roughly 12-13mpgs on a good day. Drive it like you want to and it drops to 11.5 ish. The difference between great milage and bad mileage is so little , you may as well enjoy the drive. I have a 7.3 inbound and really don't expect much better than my V10 has given me in terms of MPGs. Performance on the other hand should be a big step up from my V10. As stated previously, , i think Ford has probably squeezed as much as they can out of these 7.3s and the defined them a little for longevity.

From what I see, the chips are basically canned tunes. I give you my mods, you write a tune for it. Problem is there is no feedback and readjustment.
