Hi,

I'm still unclear as to what you mean. If you mean that the TipS robs some HP, well I agree, with some exception. Any Automatic Transmission has some Parasitic Loss associated with it simply because it draws Crank power to run the TC pump and the Servos in the Tranny. That said, Porsche adds about 8HP to the TipS cars over the Manual ones to make up for this Parasitic Loss, so there should be no Net effect.

But, your initial post mentioned robbing Torque which isn't the same thing as Power which you now state. In either event, I think I've addressed the issue, as has Porsche.

Happy Motoring!...Jim'99
