Video: C63 AMG OE Tuning / Cargraphic Long Tube headers 560 HP vs G-Power M3 570 HP
...Lol @ the C63 ricer flyby at the end. I'd say it faired pretty well though, considering the mods. I may be a little biased here (
), but considering the dollar per hp ratio between the two I'm still very happy w/ my vehicle choice. Watching this definitely makes me wish I had a DCT tranny though!

Now we need a run of a Weistec C63 vs a G-Power or any other F/I'ed E92 M3.
