Was the power delivery across the RPM range similar to stock and just a liner increase? Was there any jerkiness felt in terms of hard down/upshifts or the accelerator being overly sensitive (like in sport+ mode).

I think we have to primarily say thank you for BMW engineers on designing and putting in the amazing 8 gear transmission into the vehicle. With this race chip, the up and down shifting was very smooth to a point of you hearing the change in the throttle but not feeling any jerkiness and especially downshifts were a pleasant and well received surprise, sound wise felt like you are in an M car at the same time it felt similar to a single speed transmission.
Hopefully this feeling of my X's performance will stay
