For me, I will take the smooth running, and sure fire capability of fuel injection. I know, naturally aspirated engines are way easier to work on being as there isn't as many (if any) computer components to deal with, just turn a screw here, turn a screw there, and presto chango, you have more power. I remember when I was a kid, Dad had a CJ-7 Jeep, and that thing would run great... unless it was cold. He would have to fiddle around with the choke and pump the gas (quite a few times resulting in a flooded engine). Now my truck on the other hand, it can be -20 out and the most it will crank is 2 times before it fires right off, I love it.

Yeah Billy, I agree, you can adjust and tweak way easier on a naturally aspirated motor.

unless an engine has a forced air intake system that produces positive intake pressures it is naturally aspirated, injected or carb has nothing to do with it. supercharging or turbocharging are the only way to produce positive intake pressures(BOOST). almost like hearing someone using the term 3/4 cam.........where the hell is the other 1/4.......
