I suspect people are multiplying by 1.15, but that's incorrect. You have to divide by .85 since the 15% figure relates to the original crank value, not the WHP.

The 373hp run I would look at as abnormal because of heat soak. Gained hp, loss tq so assuming the engine compensated by pulling timing and dropping boost to generate less heat
runs 1 and 3 were after a 10 minute cool down so it showed a more regular power and tq curve IMO. But I’m not 100% familiar with how BMW programming works to counter heat soak
