You are over extending. A TBI system can be MUCH better than a carb. Once you learn to tune them, you are not screwing around with gassy hands, fuel dripping from opening up the carb, and "where in hell is the jet box?"
You fire up the computer and change the tuning.
TBI EFI pretty much solves carb like vapor lock/ fuel boil as long as the pump is set up right. Drivability is the main reason I went with EFI.
TBI is a great budget alternative if you don't want to spend more money on injectors/ manifold/ manifold mods. The only real difference, in hardware, between the TBI I use and port is just that. The Holley HP I have uses the same computer.
One last thing about EFI. Flow sizing is not nearly as critical as with a carb, especially a double pumper. You don't have to worry about "vacuum signal" as with a carb.
