The TwEECer ($350-400) works on returnless cars with the XGT1 code. (yes you can reflash most returnless cars to XGT1) It has a STEEP learning curve.
The SCT Pro Package ($750-800) works on any car and has full tuning ability and a much more user friendly layout then the TwEECer. It's still not a "plug and play" device like a chip. ANY tuning device can destroy your engine in a heartbeat if you don't know what you are doing. {/soapbox off}
Either setup is what you would need to be able to make major changes to the PCM code yourself. (I.E. engine swap, F/I, etc, etc)
