Is anyone offering any complete engine upgrades for the Panamera 4S? Looking for exhaust, air filter en ECU upgrade. And what kind of horse power increase will this get me? Anderson in Germany is offering a exhaust, air intake and ECU upgrade for 9200 euro's and the say it will get 485 hp. Is this realistic?

For the engine update, Anderson Germany is offering an exhaust system with Rennkats and software optimization. Both of them offer an increase from a total of 400 to 485 HP.
