Powerchips tune??
try contacting them Before I was going to get but stilll doubted it they said they could let you test drive one of their tuned vehicles. Decided not to was to $$$ at the time and didnt need the gains
Some people have had good experiences though from the GB a while back. I'd just do some more research on more companies before you go around for a tune. The people on the C63 forums have been giving good reviews about OETuning lately.
