I was trying to ask about your DA (of which altitude is a factor)--my measuring device records it because its impact is significant.
Anyway, on to my point: your numbers aren't great. My last M5 ran 10.33s repeatedly @131mph with a JB4--nothing else. That was on a farm road in WA state with pump gas. The F90 I had prior to that ran mid 10.5s--we eventually concluded that was down to the inferior transmission.
You should be close to or, ideally, better than that with an ECU tune assuming your conditions are similarly optimal... hence my questions.
My current M8 runs high 10.3s/low 10.4s with a JB4 (and an Eventuri intake).
