I have run both efi and carb on the same engine, actually a couple of engines now, and achieved similar results in the 1/4.....Neither set-up instantly and need some tuning.
What most fail to understand, is efi, just like a carb needs porting and the same kind of air distribution considerations to have good even plugs. You can cover it up, but to truly perform, it does need some considerations.
What I like about the newer after market efi systems is the self learning feature...Plug in the target A/F and just drive it. But there is that frustration that comes with getting it going...
