Alternator cut outs by themselves really won't improve fuel economy. It takes a system that knows the current state of charge of the battery and awareness of the brake thermal efficiency of an engine based on current load to balance the charging at the right times to get a boost in economy.

Other than braking calculating this real time is beyond most people while driving. An alternator kill switch is good for a temporary boost in power however.
