I noticed in April there was a TSB issued that covers an ABS software update to allow gear ratios above 4.5:1 in model year 2021 and 2022 4xe's. Apparently this was already applied to the 2023 model year. For those who aren't aware, this software flash is not required for the 2023, as it already allows gear ratios up to 6:1. It was only 2021-22 that had the 4.5:1 software limit.
Has anybody tried this yet? This was one thing that was holding me back from going to 38 or taller.
