I heard that you must change the spark plugs if you increase boost. any ideas? what are the best spark plugs for the V2? thanks in advance.

You mean going to a colder plug?

My guess would be that it would depend on how much boost you add. Adding 3-4 lbs? That would strike me as probably not needed. The car comes from the factory with forced induction, so it has initially been considered by GM.
