As I've seen some posts regarding this and not to be rude but the Crossfire isn't a tuning car unless you want to spend some serious cash.

If you haven't noticed, the Crossfire uses a Mercedes Benz engine so slapping on a blower or Forced Induction will not come easy nor cheap. If you're looking for a tuner, I'd suggest an SRT-4 if you have a Dodge hook up. If you want a fast Crossfire, just get an SRT-6 but it's only Auto.

Crossfires are tourers, not sprinters.
