3.21 vs 3.92: The Last Word

[SnowBlaZR2]

but at what speed and over how many miles? IIRC your 20 mpg pic was based off 49 mph whereas mine 21.5 was based off 73 mph and we all know the trickery in the above pic

That's an average speed of 72mph driving Dallas through Houston (at 9AM), not 49mph or a quick reset of the fuel mileage screen while driving slow.
Prior to getting into Houston during morning rush hour, I was at 22.x

I haven’t had the opportunity to drive several hundred unloaded miles on the highway. My truck is generally either towing something, hauling something, or sitting in the garage.

But, if I'm getting 24.7 mpg in the city...can't wait to get it on the highway someday.

I heard your truck was one of the rare prototypes that was accidentally released from the factory with 2.29 gears but was mistakenly listed as 3.92’s.

Impossible. I tow with it and it didn't blow up immediately.

4 Lo and I don't think it would have mattered what rear end you had...

Yup. 4 Lo does wonders. I’ve pulled out a bunch of smaller stumps in my yard after a tornado and with 3.21 gears even. Only damage was to my lawn.

I get roughly the same every week, 420-430 miles per tank (26 gal refilling with 23 gal). No sensitivity here, it is what it is

I get 17.5 in the warm months, but I put up 16.5 as a compromise.

Mines off since I got my 33’s. Never got my ecu corrected. I’m usually average 18+ Mixed driving

Can someone clue me in on how you are getting the mileage numbers you are posting? I have searched and found nothing. I reckon I am missing some inside joke or something.

Gotta let those 3.92s eat.

Some of these guys are messing with you by resetting the mileage while driving a slow steady speed then snapping a pic. Don't be fooled, look for an average MPG over a 100 plus miles then divide the distance traveled by the time and see what the average speed was. 22mpg at 40mph ain't impressive

This is an average over the 1st 6700 miles, mixed city driving

Maybe. Probably. But still fun. Actually I did put it in 4LO because I was on gravel and didn't want to sling it everywhere.

Turns out the metal basket was still around the root ball. I'd forgotten all about that being on there.

Here's a full tank average, mixed city and highway in North Dallas, avg speed is 39 mph over 435 miles

Looks like a CEL in the second photo.

That's pretty cool you can get the Trailer Gain in the bottom left. I haven't played around much with customizing the gauges.

The engine is off with the ignition in the run position, knock on wood, this truck has been flawless and with the new Uconnect 4 12" update, the 12" screen is working perfectly with no SiriusXM freezes.

What’s trailer gain?

What’s trailer gain?

Trailer brake control setting, amount of power the trailer brake controller applies to the trailer brakes

 

[bigdodge]

What’s trailer gain?

"Trailer gain is the amount of power a brake controller applies to the trailer brakes. It is equal to the maximum amount of stopping force for the trailer. As the vehicle brake pedal is applied, the gain tells the brake controller how much electrical power to apply to the trailer brake electromagnets."

How to Use a Trailer Brake Controller - Towing 101

Using a brake controller while towing a trailer involves setting up the controller, adjusting to the load size, adjusting braking sensitivity, manually activating the trailer brakes and possibly choosing a few personal settings. In this guide we will unpack how a trailer brake controller works...

Mr blazer will never show this screen with over 100 miles.

Nothing that you need to worry about.

That's probably true. I haven't made a trip yet that was more than 100 miles without a trailer behind me.
