200 bucks free shipping in lower 48. I tuned My g8 and Trans Am with this. You can have two licenses for two cars if you pay an extra 100 to superchips. I unlocked the G8 as I sold it but I forgot to unlock the Trans Am and it is now gone. Maybe you can call superchips and They can unlock the second car. If I remember right I had rotofab tunes downloaded on tuner for G8, I ran the highest octane tune with no problems. Best thing of all You can switch off the cylinder deactivation system!!!! Comes with cord to hook to computer and paper instructions!!! This is ready to go for tuning one car. Thanks Bryan
