It's pretty obvious. First off how do you know your detonating? Are you hearing it or do you have actual gauges. Detonation is caused by lack of fuel, so...... give your engine more fuel. What octane fuel are you running? You should be running premium gas. You may need bigger injectors, and a aftermarket ECU to work with the injectors, and maybe a fuel pump. Or you could lower the shot til you have the money to buy those.

Another approach is to run a single fogger wet system.  We assume you are upgrading your 50 to 60 shot dry system.  By changing to a wet system, you are injecting both the fuel and nos at the same time to keep the mixture more atomized and safer.

Get a fuel pressure gauge for monitoring your fuel pressure when NOS is operating to make sure your fuel pump is up to par.
