This is exactly the argument why I will resist a conversion to TB. As fantastic as the full racing package is that your great 4/4 had, my 4/4 also offers 150 HP with normal intake and a nice torque with smooth sound that lets me drive to Italy with pleasure.
I might not talk like that if I hadn't had a P4SS for two and a half years. It was great but not for everything, and it was annoying for long distances, at least to me.
