I have the works p2 flash, 3" turbo back, Buschur MAS pipe, upper ic pipe and IC. I am planning on getting fuel pump, cams264/272, and cam gears. Would I need to buy a afc or get a custom dynoflash and tune it or will these mods not effect it? I understand if I dont tune I will not GET as much power as I could. What I want to know is will it run fine and add extra hp and then tune it lets say 5 months down the road after I get a bigger turbo?
