J, If you hit the button without the NOS bottle turned on its going to be way rich because your giving your engine fuel with no air.
and if you hit the button with the jet setting from the NOS with everything on youll still be alittle rich. But thats why NOS doesn't break as many parts as some of their competers. Some of the other systems may even put out alittle more power than NOS, but NOS systems are alot easier on parts. Which will help keep you from burning a hole in a piston. If you go any bigger than 300 hp NOS it would be a very good idea to put a vac pump on your engine. good luck
