Well, I'm sure you'll need the wiring, ecm, and related components to run the SFI rather than the throttle body stuff. It can be done but it won't be a 5 minute deal IMO.Ryan

Welcome to CHR. I think that you need to hook up your vacuum advance. At part throttle when cruising you have less air and fuel in each cylinder, and the air-fuel mixture is not as densely packed...
