Does mpg improve after break-in? I am only averaging 13mpg in mixed driving with just over 1k miles on a 2019. I am running 37s so maybe that’s the culprit?

I have 2018 and I am getting 12.1.. Mainly city and light footed driving between 50 to 75 mph. Using 91 Octane 39 tire pressure. I can't never get anywhere near 14 mpg. The truck only has 1200 miles. Is it going to get better as I put more miles in? I have rubber truck mat and BAK X4 revolver tonneau cover installed if that's enough weight to cause higher mpg..
I live in Dallas - it's flat - and I (generally) light foot it (except when I don't), normal mode, and the last 17,000 miles have been indicating 15.9 mpg (I think the computer is 'optimistic.') I've had highway mileage as high as 19 mpg (indicated) and as low as 12.1 mpg (that was an outlier - 30+ mph head/cross winds). I've noticed a definite drop in mileage on any sustained highway speed much above 72-73 mph. If you are in sport mode (more aggressive throttle mapping, more aggressive transmission mapping, only begrudgingly going into top gear), mileage will suffer.
Having said that, none of us bought this for gas mileage and *damn!* it makes me smile everytime I get on it or go off road with it.
