So with the new CS on the horizon, and the fact that its nothing more than the same car just with loads more CF and a more aggressive tune...Is being ableto tune your M2 C with the CS tune something that can be done...and if the BMW dealership were to see the tune...could they deny warranty?

This is more out of curiosity than an actual plan for myself. However since AFAIK everything in the CS (engine wise) is the exact same as the M2C, having the CS tune shouldnt affect warranty...or am i wrong?
