Yep, Rob... Moscow. Didn't bring the car with me, though. It wouldn't do so well here.
Devair, your ticking is only there at full throttle? It must be really loud for you to be able to hear it at full-tilt. Do you have a scanner or any other way to monitor fuel pressure in real time? I would suspect that the ticking you are hearing is the high-pressure fuel pump (HPFP).
What year is your car? If it's not an '09, it may have the paper fuel pump sound insulator instead of the thicker rubberized one.
What may be happening, though, is that your HPFP is on its way out. It's a cam-driven mechanical pump, and if memory serves when they fail it's a lever inside that snaps. Been awhile since I read into it, though.
I don't know that changing my fuel rail pressure sensor was ever called for or if it resolved my issue (rather, the issue went away on its own and didn't come back before I put the car into storage a few months later).
'06 #101409 - Sold to move to Germany
'08 GXP #105359 - Bought and stored for 10 months before I moved back from Germany!
Stored AGAIN for two years instead of bringing it to Russia
