I dont mean to nitpick but those statements contradict themselves don't they? Better mileage and adaptability seem like great things to gain to me.
Hey maybe I'd better run for office!!
Those small benefits, to me, are no advantage at all, that's what I was trying to get at. 2-3 mpg better at best and unless you plan on switching out heads/intakes/plenums on a regular basis what's the point? I've done a MAF conversion, and while it was a fun project, it was also a complete PITA. Of course I changed a whole bunch of other stuff too which maybe just made it feel worse than it was.
