I found that about 6:1 was good for me, but as one noted, found it too lean. Since there are other tuning factors, the easiest thing to do would be to buy the Super FMU that is adjustable via a remote knob or another adjustable unit. I am running the Cartech and find it works quite well to adjust via a tiny needle valve. Some I believe are adjustable via changing out a disk but I haven't tried that type - seems pretty straightforward tho, just a little more effort.
