I would strongly advise against going anywhere near Hilltop. I took my ST there and couldn't tell any difference after "it" had been done, so I had "it" removed and again couldn't spot any difference in the bike. They don't have access to the ecu tables, so can't edit the fuel and ignition tables or adjust fuel deceleration cutoff, idle speed, fan temps, rev limits etc. Nobody actually knows what Hilltop does, but it isn't remapping (it only takes 30 - 40 minutes and most of that is 3 wide open throttle pulls on his parameter-massaged dyno to "prove" the incredible power increase). I then took my ST to Track Electronics near Norwich who properly remapped the ecu and the difference in the bike was substantial.
