I am getting ready to either order the FAST or the Boss EFI. I am leaning towards the Boss EFI since it looks more like a carb than the FAST (I want stock looking carb but with EFI advantages), but I will buy whichever will have the better software after further research. This is the Boss EFI I am looking into but anodized black. The guys at Boss EFI state they can be used on blow thru blower applications.
