New 2024 3500HD Software Update?

[Rick_]

Anyone have the skinny on the new software update that Chevrolet is pushing out only thru the dealership?

 

Also, has anyone tried GDE's Air Temp Sensor mod to see if it does in fact increase mileage?  After 6500miles of towing my small fiver (7k lbs, 12ft tall), I'm thinking I should be getting better than 8.7mpg at 70-71mpg.

What "software update"?  The Serial Data Gateway recall?  

 

Towing MPG seems fine if you are gas.  Diesel, hard to say, but a 5th wheel, 12ft tall at 70mph, I hope you aren't expecting great MPG.  Try 55-65mph to see a mileage bump.
