Now that Ruf has finally completed their ECU/exhaust kit for the 997TT I would say that all the European tuners are now in.
Sportec 550/740
Ruf 550/780
Techart 530/720
FVD 555/745
9ff 560/755
Cargraphic 544/780
Most claim they get 530-550 PS and 720-755 NM except for RUF and Cargraphic who claim 780 NM, wonder why that is?
The other thing I wonder is how many were developed on an engine dyno and how many on a rolling dyno, any ideas.
I know the RUF was done on an engine dyno with a very long harness and the ECU in the car.
