There's not a single car that I can think of (Bar the CRX HF when it was introduced, but the VX/HX do the same job with double the power) that had better fuel economy with a carb setup. And never have I heard of anyone downgrading a EFI car to carb for fuel economy, always the opposite.

my 84 rx7 would get 22hy 15-17city EFI, I switched to dual ITB style carbs with a good tune and would regularly get 30highway upper 20's city- EFI might be better because
most people don't take the time to tune the car, also i'm talking specifically about EFI systems prior to 1995 at which point they pretty much got it right. before that i think you could do better with a simple carb and proper tune
