Some very important things to running a safe nitrous tune up.
1. Retarding Timing
2. Plenty of additional fuel.
3. Start with the smallest tune up.
4. Depending on the tune up size, drop to a colder spark plug.
There are actually a ton of other things, but with a Cheater system I would start ith the smallest tune-up they suggest.
