In my opinion, nitrous is really safe and user friendly if you treat it right. You will quickly learn that most of the internet chatter and warnings are unfounded.
If you add more horsepower than your mechanical components can withstand, you'll have catastrophic failure.
If you get greedy and go excessively lean or add too much timing, you damage parts, just like tuning any engine for high performance use.
Just think of your nitrous system as totally separate tune, just like tuning a carb. If the engine is tuned properly naturally aspirasted, the only change when spraying nitrous is the timing and the fuel octane. Fuel octane is just chosen based on how much total power you want to make, or should we say cylinder pressure and temperature once everything is activated.
