3.21 gears just mean less power and acceleration, worse mpgs.
It is your decision if your performance is adequate.
Mmmm...not sure I agree. You should get better MPG with 3.21s (runs at lower RPMs). Though the difference is pretty minimal either way. But the current gearing shouldn't go bad under normal driving conditions. Especially as a DD.
Like Jadmt said- if the seat of your pants o meter says 3.21s are fine- they're fine.
Now....if you want your power back install 4.56s and drive it like you stole it. (Sorry; couldn't resist).
