Mopar 11 gear ratio

[SigLover21]

From what I understand the gear ratio of my mopar 11 is Final Drive Axle Ratio 3.92 other places I'm seeing 3.91.
In the options for gear ratio in the diablo tuner the only one close is 3.90 . Is that good enough? IDK? Maybe some
of you bright car guru types could help.

thats enough, but there is no need to adjust that setting for the stock gears, it already knows what they are
