Nitrous Oxide System

On EFI engines, the nitrous can be injected directly into the intake tract. A tuning tip when using nitrous is to retard the timing to prevent detonation. One rule of thumb is you should take out 2 1/2 degrees for every 50 hp of nitrous. Most of the aftermarket ignition companies sell electronic switches to retard the timing when the nitrous is activated. This allows you to keep the timing at your normal setting for those times when the nitrous is not in use.
