at this point you only have one choice. Bully dog.
Edge is coming out with a 2006 LLY/LBZ Juice in June...
Edit: actually you have two choices, Bully Dog or the PPE Duramaximizer. The Duramaximizer simply increases fuel pressure...which IMO is not a good way to get more performance. If you *need* a chip now, go with the Bully Dog....but if I were you id wait for the Edge to come out.
