All the turbocharger does is increase the amount of air entering the combustion chamber. Either the computer, by keeping the injector open longer, or some other mechanism, adds fuel to match the extra air. Stopping the additional fuel altogether, with no other compensating changes, could cause you to run dangerously lean.
