Sucks the only info in gauge mode is the trans temp, when the OBDII Aeroforce gauges show all kinds of info. No reason the OEM display couldn't do the same.
I always keep mine on instant mileage. Helps encourage me to keep my foot out of it LOL. And I pretty much never look at my fuel gauge, I always just fill up when I hit ~100 miles to empty.
Few times that I have been offroad I'll use that screen.
When I trailer I use the trailer screen. Do NOT want to watch the MPG while towing LOL, and the trailer screen shows the trailer odometer, the trailer brake output level, etc. And it's a nice reminder I have a trailer hooked up, because sometimes it's easy to forget with how nice the Raptor tows. When I don't notice that green instant MPG bar in front of me, it's a quick reminder there's a trailer out back.
