The seller emailed me today and said the tuner was ready to be unlocked. So I plugged it in to my computer and ran the updating program. Now the tuner says it hasn't been used, so it looks like I'm good to go. WOOHOO!

After the tune:
OMG this tuner is amazing, it seems like a different car now. I took off in manual mode, hit 2nd gear and the car took off like rocket! It shifts like a fully manual trans without the clutch, all the shifts are firm & quick, with no lag at all like before. And at light throttle pressure it shifts nice & smooth just like stock.

I set the shift torque management at 50% above stock (It goes all the way up to 200%) and I couldn't imagine what it would be like any higher. I think the front wheels would come off the ground, lol. I also removed the AFM (cylinder deactivation) and the car feels so much better when cruising in auto mode. Sport shift holds the gears longer now, and selects the right gear when entering & exiting the corners to keep the motor in the powerband. It seems to have more power too, the rear wheels were struggling to get traction most of the time at anything over half throttle. I highly recommend the Superchips tuner, it turns the G8 into a wild animal!

I know it doesn't seem logical, but adding more fuel will make the engine lose power. Decreasing the fuel to air ratio will allow it to make more power if the ratio is too high. When you install a CAI the MAF senses more air, so it increases the fuel to keep the ratio at the amount that it's tuned for. To get more power the tune has to be leaner on fuel, which is what the CAI specific tune will do. But it can't be too lean either, that will cause knock which can damage the engine.
