Gear Ratio Help

[Cuboidnoise]

Wondered if someone could point me in the right direction.

Ive just bought a sv2 second hand. Its got a 83 tooth to 23 pinion. Which on the chart in the manual is 9.32

Ive got a speed passion 13.5 turn v3 competition motor, according to the chart i should be aiming for between 4.8 to 6.0

This means i would be running a 32 pinion and 76 main gear which would give me a 6.13

should i do this or can i get away with the current gearing of 83 to 23????

Any guidance would be awesome
