I'm not overly impressed with the Hartge figures.
Maybe if it's a 82hp gain over stock - then we are talking over 700hp at the crank.....!
No they are saying the M5 is already making 640hp stock since it does 540 whp. This tune does nothing.
As a comparison, the CTSV which advertise 555hp only dyno 490 whp.
2012 GTR Which advertise 530hp only dyno 430 whp.
BMW is really working their magic
