Kelleners, acschnitzer etc are all around 620-640hp, manhart racing told me they should be ready with a 730 hp step next spring 2013 (reenforced,rear axel, reenforced transmession as well..)

It is obvious that the x5/6m engine is over 700ph, but the better/newer m5 f10 engine wasnt able to crak for this power output...
Very curious who will be the first one with a serious tune over the 700hp...
Manhart, Schnitzer,PP-all running exact same ECU tune. Not a custom in house tune. No one has one. They come form the same source. I have the EXACT tune, downpipes and exhaust on my car. Car is ridiculously fast. Will leave a stock M5 in the dust. Greatest challenge is launch.
