I do think that the reliable 39 bhp boost in combination with (presumably) extra cooling capability and improved engine management is one of the advantages being overlooked here. If the CS cools 1/2 as good as the GTS, then you won't have to give a 2nd thought to engine temps. The same cannot be said for most aftermarket tuned turbo cars on track.




The M3 CS tune is available in the aftermarket now, so it's highly likely the M2 CS tune will be cracked and available widely at some point.
