How much gain with lower gears?

MAPS said

Oh God, I hear you 100 % most people will not believe you but doI , I swapped 3.23 for 4.10 and they actually felt the exact same, I did not feel any difference let alone that "Smash" off the line with the lower gears (4.10) Even on the highway wasI doing about 2500 (give or take 1-200 rpm difference) at 60 mph.
Finally someone who see what felt.

At Zero-TC slip, your 2500rpm and 4.10s translates to a 33" tire. With 30" tires this computes to 10%slip.
At Zero-slip your 2500 and 3.23s translates to a 26" tire. With 5%slip, this would be 27.3s.
But going down the hiway, the TCs often/usually slip in the opposite direction; with the actual running rpm being less than the Zero slip.
If we toss 100rpm into the mix, then ;
at an indicated 2500, and zero-slip being 2600, then;
4.10 needs 31.8s, and
3.23s need 25s

If you used the same tire for both, then the TC .........mustabin IDK, maybe toast? Or real loose
