Who's tune are you going with?

hamann1000

are you doing new fuel injectors and fuel rail? from what I have been told anything more than a pulley, tune, and headers will need to upgrade the fuel system or chance running fuel injectors static or blowing the #8 that seems to be notorious for being fuel starved
