If the EFI guys spent as much time learning carbs as they do EFI they wouldn’t change to EFI.
A carb is self tuning IF it’s close. In fact, Ben Strader of EFI University (a guy who isn’t a run of the mill tuner by any stretch of the imagination) finally got an EFI engine to beat a carb’d engine and that wasnt by much.
If you looked at the system, it looked carb’d. It was a tunnel ram and it was essentially was carb’d because all the fuel went through the throttle bodies.
If you’re carbs are even close, you can get almost everything EFI will do without the rest of the bullcrap. But you’ve got to put in the same effort with a carb as you are willing to do with EFI.
