Alright...the car is back with the newest update. They also changed the diff fluid as I complained about the sporadic groaning sound when turning in the past. The system prompted them on the update necessary. From my brief drive, the lag is definitely still present, but does seem to be significantly reduced as reflected in other posts. I believe the car is downshifting faster, especially into first....thus helping with the downshift lag. We'll see how much it's really improved after further driving. They said they think it was ISTA 34.0.0.5...but were unable to pull it up. In any case, the SA said it was the latest as the system is updated real time with anything new.
