I just upgraded from 2002 Ultegra crank and I noticed that after the first couple of rides, the bolt that attaches it to the bottom bracket gets a little loose. Is that normal for a brand new one? I used the same bottom bracket from my Ultegra crank (octalink). My LBS also told me to check it after each ride for about a week.

If it is tightened properly and the crankarm is not damaged it should not come loose.

If the bolt is not greased yet, grease it. That'll let you tighten it to the point of being truly tight rather than "I can't go any further because of the friction between the threads".

Beyond that, more torque and blue loctite are your other options.
What kind of crank fixing bolt are you using?pedalAZ

I've got Ti crank fixing bolts, so when I am re-installing the cranks, I tighten them up with a steel crank fixing bolt first, to get them on the tapered spindle nice and snug, then I back off the steel, and insert the ti bolt (with ti-prep anti-seize) up to its torque setting.

However, since you have the FSA carbon pro compact, you are either on Octalink or ISIS, where it should seat at the end of the splines, unlike a square taper fit. I don't have experience with these.
