I think you need to invest on some lead for your right boot
Seriously I have a naturally aspirated V8 (granted it is only an S4) and a V8T diesel A8. The difference is the S4 feels and sounds fast, where as the A8 simply is faster without the "fuss" or maybe "fun".....
The current loan car is the latest version of the 4.2TDI, ~380bhp..... maybe because it is a loaner (and they are always faster right) but it seems to trouble the traction control easily on a 4wd car with huge tyres
Is your car on autotrader now?
