Forgive me if this is wrong as I'm not so sure about 1j's, but for 7m's, pulling fuel doesn't raise fuel cut. Fuel cut is the amount of air is greater than the ecu has a map for so the injectors can't keep up.
7m s are maf cars.. 1jz are map cars. They don't have a maf measuring air flow. Its based onmap load. So bye pulling fuel your tricking the map voltage
