I just talked with Gary at Diablo Sport and he told me that you CAN use the LS2 Predator on another vehicle IF the original owner of the Predator has taken out his tune. Otherwise it is locked to that vehicle. I was planning on selling my Predator after I tuned mine as I am sure others are planning. If there is anyone that knows how to flash the predator to use in another LS2 vehicle (without having to take out the tune in the original car) please post it. I have seen many questions on this but not answers. Which is why I called Diablo. Also. The LS2 predator is the first Predator you do NOT have to ship back to them to upgrade. All upgrades can be downloaded from their site.
