nitrous 929 help

heres the deal, i have a cbr 929 that im putting nitrous on, ive already got M4 full exhaust, power commander 3usb, lowered and stretched, zzz 530 chain, -1 +2 sprockets. i ordered the ZEX efi dry system (should come in sometime this week) my main question is do i need to get a dynojet hub with map switch for all motor map and then nitrous map when on the bottle or can i have just one map that will run a little rich off the bottle and perfect on bottle. i only plan on spraying with 30 shot. but if i can get the hub and "safely" spray more with a custom nitous map it might be going on my xmas list. what do you guys think?
