I'm a newbie, but have visited your websight many times in the past and have been impressed with the info given. I own a '00 Cavi w/ 2.2 L was wondering if anyone knows about the g-box @ next level perfomance and if it reaaly works, already done the pacesetter ceramic header and had a noticeable increase in power Anything to help me get more power would be appreciated ( I know I should of held out for a 2.4 or Ecotec) Thank you.

No, whatever it is, there is no chip, module, or any device that adds power to the car. The Jet and Venom are junk, as I'm sure this is as well.
