Different strokes for different folks. These "arguements" are for show and for discussion. When ever 2 guys get together there will always be discussions of who's is faster, better looking, bigger etc: it's car talk. I for one always enjoy a good debate, even political, you share ideas, opinions and hopefully both will walk away with more knowledge than before entering the fray. I for one always learn something or at the minimum the urge to do more research. Then do or beleive what I want.
The Feb. 2009 Kit Car Builder magazine has an interesting article where the Dynatek FI is compared to carburation on the same motor; mileage increased from 12.66 to 19.02 and there was a 40hp gain throughout the rev range on the FI system. Good article both sides should review it.
One comment, in one of the post a person said all the emissions standards came out and then FI was born. FI has been around since the 50's and maybe earlier, the computer is what made FI work.
