I know it's a dumb question because most people don't care about gas mileage.

But in general, which one *should* be the best on gas mileage?

I'm thinking F/I, since while cruising you're not necessarily going to be in 'boost', whereas N/A, the power is always on tap, which means more fuel most of the time.

Thoughts? I realize it's not going to be as good as stock, but it's still a reasonable concern.

I ask because I'm trying to decide which way to build my motor, but I'll also still be driving it daily...so it really is a concern to me.

This is a very vague question. But you can achieve very good gas mileage with both n/a and f/i depending on how well you tune and what you tune with.

Hmmm, well I don't know how to phrase it to not be so (as) vague.

Thanks for the reply though.
