Welcome to the club!
The standard TTE supercharger is good for roughly 210 HP, you can also get exhaust, ECU upgrade, supercharger boost upgrade, induction kit, manifolds and many more things to increase power even more. Mark at TDi is definately your man, speak to him and I'm sure he can sort out your performance.
I have a Morpheous Geodesy in my car, at the moment it is connected to the cigarette lighter but I will be wiring it in permanently soon, when I have it wired in I'll post some sort of description and photos on what to do.
