Denny - this might make a good "different" topic.
But since you asked, I fear your comment may have been taken out of context.
Throttle body injection offers little or no benefit over a carburetor other than to "inject" (pun intended) a degree of difficulty above the average enthusiast's level of expertise; and a cost definately above the average enthusiast's budget.
Port injection will perform better than carburetors tuned by the average enthusiast, as the average enthusiast either does not understand "pulsing" or if he/she does understand, does not have the necessary equipment to tune for pulsing. Port injection is not effected overly by pulsing, as only air is flowing into the manifold runners.
I am not convinced that even port injection will significantly improve power/economy over a properly tuned carburetor. However, there is NO question that computer controlled port injection can significantly reduce emissions.
