there is this "supercharger" thing on ebay that claims to give a 10% increase in hp and a 30% increase in gas mileage. Does anybody know if it actually works at all or is it just a rip off? i dont really care so much about the hp gain but if it increases fuel efficiency at all then i guess it's worth it.
