Can someone give me an example of how well changing out the gears will improve my performance like there before and after 0-60 time or 1/4 mile and before and after top speed?
Adding gears is torque multiplication. Like riding a 10 speed bike. In the lower gears (which would be a higher numbered gear, 4.30) you can take off very easy & pull heavy things. In the higher gears (which would be a lower number gear, 2.50) it is hard to take off, but once going it is easier. That is a broad example of using a 10 speed bike. The difference in gears in not as much as a 10 speed bike. 4.10 gears are easier to take off faster than 2.79 gears.
