It revs ok but it lacks bit of power i would say it's got 80% of power I have replaced spark plug,injectior, air filter,belt and rollers Any ideas?

The first thing that popped into my mind was "it's a choke issue" but I haven't a clue how an EFI handles that. I too have a '13 GTS 300 with about 5k km but she starts and runs well, so far.
