One thing I noticed recently when I was going over the data is that the carb made 50 hp more than EFI at 5000 rpm. At peak power the EFI config made more power than the carb. I'm not sure what to think about the 50 hp difference at 5000 rpm, could be some sort of wave thing that happened for some reason. The intake was the same but perhaps the carb was just doing a better job at that RPM than the throttle body?
