is Final gear ratio important when using slip diff?

[BP-Revo]

Well, when you are geared for more speed and apply full throttle, there is usually more torque on all your drivetrain, and more force lifting the front end.

So, this both makes the center diff diff out more and will make the slipper slip more than than it would if your truck was geared for less speed given the same slipper setting.

So, in a sense, it "does" matter, but it also depends on how smooth your throttle finger is, how much punch control, etc.
