Says 425 at the wheel 93 octane on a 2015 F80 M3 and 400 wheel, some inconsistencies on S55 dynos (someone please confirm a better source as these were the quickest ones I could find).

Bootmod3 says will do 500 with a tune.

This is before the huge headroom in the S58 with a simple ECU tune to push it to 600whp...same tune from PTF for the S58.

Thanks! So it looks like the ~80 hp gap is legit averaging the spread and fuel type.
