I think the S55 has this torque as it has because more torque would make the driveability not betterr. |
Well, AC Schnitzer has managed to delimit the M5/M6. And they use a piggyback. So, let's wait and see on that.
Did you also read the article in the same magazine abouth the Manhart M6? What did they say about the driveability and power delivery of that engine, which has been tuned even further...
Yes, driveability certainly can suffer after tuning. But not necessarily
We will just have to wait and see
