I went 3.92 on mine and glad i did. When I did the math the extra 1MPG i'm loosing is about $125 a year. I drove the 3.21 and then the 3.92 back to back and you can feel the difference. The 3.92 is much more fun Imo. I'm getting a solid 17mpg on my 19 ram after 1200 miles with one long road trip. Highway the highest I got was 21.6 of solid highway driving from Columbus to Indianapolis.
