Dry is way safer than wet. If hooked up to your TB you have chances it will condisate, leaving puddles on the intake runners. I see a lot of people running the nitrous directly into their lower intake so less chances of this backfire happening. If the nitrous puddles onto the intake it causes it to all of a sudden charge and backfire which will lead to blowing your internals out your exhaust or wherever it may want to exit. Not a pretty site.
As for the dry system you are dealing with nitrous only and the only thing you need to do for fuel is upgrade the pump or run bigger injectors so you don't have any predetonation.
You can have a nitrous backfire with both systems but you are less likely with the dry.
Remember the more air you run in your motor you must compensate with more fuel too. Better to run rich than lean anyday.
