It is safe to spray a wet nitrous setup. I don't think it is "safe" to run on a dry kit, but I could be wrong (I recall someone saying that you can tune your a/f ratio and run a dry Venom kit, but that might be a whole different ballpark).

As for what RPM you should tune your vafc to xover at, remember that nitrous is very similar to an N/A motor because it isn't forcing mass air in the motor.

My take on spraying at real low rpms and in high gears is that it lugs the motor, putting a lot of stress on it since the rpm is going to climb slowly.

-Tune the vafc, check the nitrous with the new fuel settings via a WBO2, add fuel if needed.

-whatever works the best for your motor off of the bottle.

-Supposedly engine load is too high, but you can try it if you want. Also solenoid coils like to fail if you spray for too long, which is likely to occur if you do a top speed run starting from 0 mph.

you can get one or just get it dynoed at a shop with a wideband. The shop that tunes your VAFC will have a wideband and if they don't they shouldn't be tuning your car.
