I thought your car didn't come with PTV? Maybe i'm wrong. I'm just going by the option sticker picture you posted earlier.
Track time!!!
There is a definite improvement with the dynamic engine mounts and TQ vectoring. The car turns in well but when she gets loose, she gets loose. I think there is a slightly longer threshold to push the car with this technology which makes the car feel more stable in hard cornering.

I would stay well clear of the 550 BHP mark given this new piece of info:

Latest from the engine dyno.......
Following on from Porsche engineers telling them "this engine is not for you" RS Tuning got a willing customer with a new DFi turbo.
The engine broke a conrod at the 550hp level, I don't know the protocol for the engine dyno testing but it is quite rigorous with 3 days testing....
So the weak points are the conrods, pistons and head gasket.
RS is re-engineering this dead engine for the customer who has a nice shiny new 997tt.2 sitting high with no motor
They are making it 4 litre, special boring process, having different head gaskets made and Carrillo rods - They are not over cofident that the re-engineered lump will last very long..... It seems the new engine will need quite a lot of development to become reliable when tuned..

We are in the process of designing new headers. Our initial test headers were a bit too large and caused a loss in bottom end power and torque. We did have a nice increase in top end power which leads me to think that the OEM headers are choking the performance at our current power level. We will be offering a few different sizes depending on the application like we do for the other cars. There is not one perfect size header as other suppliers may think. The header diameter and flow have to be balanced to match the turbo size and overall output / VE of the engine in order to be optimized. Here are a few photos of our GEN 1 design.
I like the craftsmanship.
