OEM starts at 48v and then drops over time as the FICM fails due to crappy components and workmanship. At some lower voltage damage to injectors is reported to occur.
The higher voltage FICMS (usually 53 or 58v) obviously would provide more of a voltage buffer before low voltage occurs, but they are also noted to have helped stimulate a lazy injector experiencing stiction. The higher voltage FICMs are also thought to move the injectors a little faster, possibly offering a small performance gain.
Hope this helps.
