If stock gearing for the Slash 2wd is (48p) 19 pinion/90 spur (SOMEONE PLEASE CORRECT ME IF I'M WRONG)

I'm looking for a bit more oomph in acceleration/torque for jumps after tight turns.

And second to that I'm looking for longer run times/lower heat on the stock motor/Titan 12.

Would a 16 tooth pinion be good? 14 too low?

I don't know how to read/understand the final drive ratio stuff. I know if you go too low in pinion, it overheats the motor as well.

Thanks
