That is normal with these extra breather mods. You gain alot of top end and low either barely changes or you lose a little until you tune. I would say dont tune until all of your breather mods are done. CBE, Intakes, and some form of hfc/tp/lth. Retuning is a waste of money and you will be happier that you waited.
