Same here with intermittent ticking, but I've found that after the motor has been running for more than 20 minutes at highway speeds (i.e. ~80mph here in FL) it goes away.
Mentioned it while I has having my HPFP replaced last week, and they couldn't find anything specific. If it gets more pronounced I'll make an appt to have them find it and get rid of it, but until then I'm happy.
