Yes, but still need to setup the non-nitrous stuff first. A pressure reading at the boost level being run would also assist in selecting the nitrous jet. So lets say at 20 PSI the pumps output is 100 PSI. So you figure your jetting at 100 PSI pressure. More than likely what will hapeen is when the button is pushed the boost will climb and deliver higher pressure on the alcohol, but thats not an issue too much as adding the extra nozzle for the nitrous should bring pressure down a tad.
When I ran it using the FAST, I used the correction to tell me which way to go with the nitrous fuel jetting. Meaning is the car runs zero correction when I spray alky+pump and it now needs to add lets say 5% correction with the nitrous, it needs a larger fuel jet to get it to zero correction.
