So buying one used is out of the question?

yes & no. The very first model for the C5... is strapped to one car. The only way it can be used on another car is to send it back to Daiblo (and there's $$ involved).

The newer ones supposedly will work on a different automobile - assuming the original car has been restored (from that specific Predator) back to it's original factory program.

Best to call Diablosport with the model # and serial number of the unit being sold used.

My diablo instructions says you can restore original tune to your car and then you can use on a different car... have not tried that tho

I haven't seen anyone use one on more than one car.
