Hey! Glad to hear that I'm not the only one hearing that. At first I thought it was valves chattering, but it only does it under brisk accelleration. Then I thought it was knocking (i.e. detonation). That would be unlikely since it seemed to happen even when the engine was cold. I bumped the octane up on the next two tanks and there was zero difference. I doubt that the sound is knocking.
Since I only hear it when I give it a lot of throttle, I'm starting to think that it might be related to the EFI system. Maybe the fuel pump ramping up? I noticed that you can make a similar sound (one click at a time) when the engine is idling. Throttle up and back and you'll hear the same click sound on the way up and one on the way down.
I'm going to keep looking, but for now I'm thinking that its normal.
