Only problem efi is not more complex than a carb IF you know how to tune. Too many guys who don't know how to tune carbs slap efi on because they are told about all the benefits and reliability/tune capabilities. those same guys start to make power and blow **** up. Every single car I've seen at any local drag strip (we are spoiled and have 5 close to me) that have blown an engine were power adder cars with efi period. Around here there are not that many fast guys still running nitrous but all of the ones I know have a carb under the hood.
