2013 BMW M5 - RPI, Gruppe M - Dyno Results

Went to Goodspeed Performance today
They have a Maha dyno, gas was only 91 octane.
Run was in gear 4, car in manual mode.
Settings were in efficient and comfort (Said Sport mode doesnt effect HP)

Results:
To the wheel: 459HP, 446TQ
To the crank: 556HP, 510TQ

Wheel Dyno:


Crank Dyno:


No before runs in stock format, so no way to tell what these modifications did as far as "gains". This just shows what my car is at. Sorry to disappoint on that front.

Also, this dyno is supposed to be highly accurate and doesn't have massaging of the numbers available through a manual process of inputting in a "Corrected" skew.

There is a dip in the curve, which is directly related to the 91 octane opposed to 93.

Let me know your thoughts. Thanks.
