?? From a 3.0 litre motor ?? I ran 19psi on the stock turbos with meth, dps and intake on my n54 335i and could only manage 412/446 wheel HP/TQ. The s55 M3 is going run ~ 12-14psi to make 415 crank HP from slightly larger turbos than what is on the n54 (not too much larger to prevent lag, along with the third electric turbo) and so bolt ons will not get it anywhere near "High 500's low 600's". You'd need three larger turbos to do that lol
