Rogue300

So I have an NA 95 300zx and i bought it with the motor already bored out. Ik it has wise co pistons in it that are larger that stock, do I need bigger injectors and a tune if I wanna make more power? Cuz rn it feels kinda sluggish. Might be running rich or lean I’m not sure. Was thinking about putting 370cc injectors in it from the tt but I’m not sure. Please lemme know if u have any ideas
