I heard the rumor and was thinking that maybe they would remap the ECU for faster power delivery. Meaning that you would still have 503hp from mile 0, just delivered more gently. But that looks like is not even the case.
On my S1000RR, RPMs were limited during the break-in period. I thought BMW cars would mirror that approach... NOT.
That explains the number of people posting 1/4mi. times and 0-60 so early into the release
