Have you had the TSB upflash done? Or is yours out of the date range?
Mine seemed to do similar just a bit lower down in speed, but yes, I know what you mean. After the TSB flash, plus a reset of the learning cells at my request, it seems to coast a bit better in the range just below what you mention.
