You cant adjust timing with an SAFC. Also, cam timing isnt what makes a difference, its ignition timing.... Two totally different things, and the timing really wont do much in a low boost app. such as this one.... Just get a set of 450s, an AFC, and ditch the FMU... There is no need for an FMU if you are running the AFC with properly sized injectors.....

PS... See sig for my reccomendation
