Look at the diference in 0-200 for the 997.1 Carrera S and the 997.2 Carrera S with PDK, it's almost 2.5 seonds. Surely the addition of PDK has a lot to do with that huge difference, and not just the power gains. The 997.2TT with PDK should be markedly quicker than the 997.1 unless Porsche has throttled it back due to the GT2 market.
