I had a T34.48 on Greys NMS Live map on my old 3dr and it was superb as a raod car as people call it, very punchy did ease off at the top end.
My car is now with Karl having alot of work done to it which includes a new TT T34.63 with Siemens etc etc so i'll let you know how it feels..
Quite lively i'd imagine with 2.2bar peak up it's ass.....
