If your asking in terms of what it's designed to do then yeah, i never had any problems with fuel cut. However they don't really do anything but bleed air from the map sensor an a electrical fcd is just gonna clamp the signal sent to the ecu.
The downside with using any fcd is that you aren't doing anything to sort the fueling past the point of factory fuel cut, if anything the scaling effect on the airflow signal is alway gonna tell the ecu less air is running through the engine that actually is. Which often ends up in running lean.
My advice is to always check your afr's with a wideband and adjust the fueling accordingly
