SCt X3 tuner question about Axle Ratio
I got an X3 tuned by rogue performance for my '05 ranger. I got an economy tune downloaded right now, and it drives so much smoother. However, when I go into my tunes and do the "adjust options" feature before applying my tune, i see that I can adjust my tire size and axle ratio. My truck has 4.10 gears stock, but the 4.10 selection box in the tuner is not checked, but "stock" is checked. So should I change this to 4.10? I changed the tire size already to my 33x12.5 tires.
