The code is for running to rich, a leak when off boost would run lean but would run rich when on boost. The leak would have to be down stream of the throttle for such effects at idle or low power. When on boost, a leak anywhere down stream of the turbo would run rich. A leak downstream of the TB for off-boost conditions would run lean. Such a leak could be detected with a spray. That suggested spray could damage paint etc.
A leak in the hose to the FPR will run rich on off-boost conditions and lean on on-boost.
