What is the best setting for the best economy using X2 and Commander. What has been everyones else's experience?

 

I'm currently testing the City MPG file download for the X2. It's looking good. But I've only gone through 1/4 tank. It's tougher to measure during winter here in WI. They change the blends all of the time since we have such a fluxuating temps.

But you're going to need to remember each truck is a little different & so will be your driving style. You'll have to figure which works best for your.

Before the new City MPG file, 60hp was the best for me when I had 1500-3000# behind me. Empty I was using the MPG file. The combo of the two worked the best for me.
