It might be a while before someone will think about tearing apart a new motor for more power. Particularly one with the power already available to the 5.7L hemi. What will be interesting is what types of programe will be poping up for upgrading fuel curve, tranny shift points and shift firmness. Will it be a modified Mercedes performance tune? I would think it would need to be, if the electronics and tranny are Mercedes design. I know there are lots of aftermarket tuning sources for German cars. It may take a while for someone to come up with the right chip or program for the 300C (American V8, German Tranny and Computer).
