I always update my customers to the latest software from ISTA/P 46.2 before tuning the car. That way it's the latest and freshest from BMW and their bug fixes are incorporated. Also a good measure to update the DCT software level to match with the DME if it's not already on the latest version.
Usually this is customary, but since this was a 6MT car - no need.
