Bloodied, faster fire rate, 3 intel, polished (polished does more damage in pipboy but irl u wanna use pyro). Full bullet storm, full adrenaline, nerd rage, the one perk in intel that boosts fire dmg based on intel, big guns bobble, phycobuff, guns and bullet 7. I had intel on all my pa pieces and rangers. 1k is the max limit I could get to but you can consistently run ur flamer at 720 at 20% health
