target boost is the boost that you may or may not hit. say for instance your tuned for 18lbs target boost but your hitting 17lbs or so, its fine but 18 is your max. anything above target boost is over boosting. thats how i understand it. i am no tuner, pm invar hes pretty good with these types of things.
