Does the rev limiter pull fuel or spark?

A low pressure safety switch wouldn't work in this situation (where the PCM pulls fuel)...the fuel gets pulled by keeping the injectors from firing, so if anything, your fuel pressure would increase in the system since it isn't going anywhere. The PCM isn't shutting off the fuel pump, and as long as that's pumping, you'll have at least 50+ psi in the rails...

Actually, the problem would be if you were running a WET shot, not dry. There is no harm in pumping unfueled nitrous through the motor. There would be a lot of harm in pumping a fueled nitrous shot with normal engine intake air not being fueled. In any event, the proper way would be to set the factory PCM rev limit above the nitrous rev limit.
