Default modified stock injector scaling on street tuner

The Modified stock injectors were flowtested and were rated at 710cc at 40lbs of fuel. My question is, what should the injector cc rating be at with our 3 bar fuel press?

Also, I was reading the streettuner guide, and it said for injector scaling you must take the previous injector size in cc and divide by the new size, and then multiply by the old scale value and you will get the new scale value. Well my question is, what values have you guys used for this on your setups?
