Encouraging to hear, I doubt the 91ACN tune would be anything to worry about from a CH perspective. I have heard many similar stories like this, not with as many miles, but same conditions.
I doubt that BMW made any changes to the S55 design as they were probably focused on getting the B58/sS58 platform going.
