Peak torque figures rise from 476 pound-feet at the wheels to 530 pound-feet at the wheels. The torque gains are through the entire curve, very impressive.
Now imagine all this with a tune on top. Easily over 600 wheel horsepower, all with bolt ons. The S63TU despite being in a higher state of tune from the factory than the S63 is responding quite well to bolt on modifications and not giving up much to the larger AMG M157 especially considering this is still early in the tuning phase for the motor.
