Stock 3.45 Gears with 35" Tires - Noticeable Performance hit?

Wondered if anyone here that has upgraded to 35" tires on 3.45 gears can comment on how the performance of the vehicle changed.

From writeups I've seen here, once you put 37" on a Rubicon with 4.10 gearing and the shift points in the computer are updated, that setup runs beautifully with little or no sense of "lost power."

I am wondering how well the Sports and Saharas are fairing with a slightly more conservative 35" tire on the 3.45 gears. Did you get shift points adjusted?

Thanks!

I can tell you that my Rubi with 37” tires feels better then the wife’s with 33” tires off the Rubi.

As a disclaimer though the Rubi has been doorless and topless for the last 2000 miles.
