cheaper yes, cheaper to inject, no.
Im switching to it right now in my race car only, and for my power, I have to get the fuel system of a damn semi truck to do it. Of course its fine in a daily, but youll only get about 20mpg if you are used to 30 mpg. Whatever setup you have now, you have to flow 1.5x times the capacity to support it at the same power level.
