For reference purposes:

Stock gear ratios are as follows:
A=3.09:1
F=1.89:1
N=1.26:1
V=0.93:1
ZD=0.71:1

For acceleration purposes, you want higher ratios.

In this transmission, ratios are:
A=3.09:1
F=1.89:1
KA=1.41:1
R=1.08:1
Z=0.79:1

What you see when driving is about 300-500 rpm higher at any given speed, especially in 3rd and 4th, so it allows the engine to be better into the torque/power band.
