Hi,
Have a look at a gear ratio chart for the car you are running. There is a serious difference between the two ratios you have above.
Assume internal gearbox ratio is 2.6:1, but check for the car you are running.
23/83 overall is 9.3
25/76 overall is 7.8
The difference between then is far too much, to be usable on the same motor.
(9.3 is gearing for 7.5t motor, 7.8 is gearing for 10.5t motor.)
If your gearing is in the right area, try a pinion up or down and see how the car reacts.
So in the above going to 24/83, which will give more top speed, your overall is now 9.0
