I am going to purchase a fmu. They come in all different ratio's. What is the best ratio to get? I can get one that is 1:1 boost to fuel or the vortech universal which comes in a lot of different ratios. Also what is the appropriate fuel pump setup? Just a add on inline? Or drop my tank and just replace the stock one with a high flow? It seems easier to put one inline. I will be using 550cc injectors. And while i'm asking...i am debating between greddy e-manage and apexi safc II. Can I use the greddy emanage to adjust my fuel curve and use it for a digital boost controller as well? Is it a better tuning tool than the apexi? Please give me some opinions or information. thanks.
It also looks like you can use the greddy e-manage to retard timing? Is that also true? If I can use the E-manage to tune my boost, air/fuel ratio, and my timing retard, then I am definetly getting one.
