Imagine AT 4.88 start from zero and in 55km/h the AT 4.88 shift to gear 2 .
AT 4.1 will be slower till 55km/h but from 55km/h to 65km/h the AT 4.1 is in gear 1 and AT 4.88 is in gear 2 and the torque of AT 4.1 is higher in 55-65km/h range.
This happen in all shifting range and overally FD 4.88 will not make it faster than 5% in 0-176km/h.
Going to higher FD will not help you.
