It doesn't quite work that way. You can't change all the parameters in the map that you would want to when switching from pump to race gas by only using the i/s/s# knob.
You can however raise and lower boost to suit your particular weather conditions, gas consumption needs, etc. with the i/s/s# knob and some clever tuning.
