Gun Boost only increase the damage of the weapon its attached in to.

Power up increase damage of weapons you currently wield, but you need to purchase the part-equiped weapon first (ex. you attach the power up part to dual infinity final, then you need to buy dual infinity final as your secondary so your primary and melee can have the damage boost)
