@syswizard, Why not 8 speed PDK on a 718? First understand that the reason for having a transmission was to keep the engine at, or near, its performance peak. That is typically defined as the peak of the torque curve. When you have a wide flat torque curve, as do most turbo engines like the 718, the peak torque is spread over several thousand RPM. I did not look up the 718 specs, but torque is probably flat between around 1500 to say 5500 RPM. So you really probably don't need a PDK with 7 gears let alone 8. Upside is of course the fact you can add overdrive gearing and under certain conditions improve gas milage by allowing the engine to turn over at lower RPM. Less air moved through the engine less fuel consumed. Anyway, hope this helps.
