The part about ignition devices. Are Power Commanders legal? All modified bikes with factory fuel injection have to have this.

Yes, PC's are legal for FI'd machines just as well as FAST performance aftermarket carbs are for naturally aspirated machines. This makes the field even putting the load on each tuner and rider to be better than the next.
