I totally disagree. EFI is so much simpler than carb tuning that you can't even compare the two in the same breath.
It is a common misconception that you have to re-map the computer when you change something. That is flat wrong. An EFI system is engineered to keep the engine running at optimum fuel / air ratio regardless of atmospheric conditions. Therefore if you do things like changing out an air filter or add a performance exhaust, the EFI system automatically compensates and keeps the A/F ratio within a set range at all throttle positions and under varying loads. A carburettor simply can't do that. A carb is at best a compromise, it can never constantly adjust itself like EFI can.
The reason that many people re-map their EFI system's VE (Volumetric Efficiency) tables is to remove lean running under certain conditions that are put in place for emmisions reasons. Most have been sold a bill of goods, that they need these piggy-back boxes to adjust the system for the pipes they have installed. To a very small extent, that's true. But only with regard to absolute peak performance across throttle position and loads. For 99.9% of street riding the stock maps will work just fine, regardless of which pipe has been installed.
For me, even if I have to hook up a lap top to my system and take 15 or so seconds to download a new map, that sure beats the crap out of busting out the tools and rejetting a carb (or multiple carbs), where you're looking at an hour minimum, and you'd better hope you guessed correctly on jet size, or you'll have to do it all over again.
