~20 mpg

i'm running off the 12:1 vortec with no tuning. also I go into boost alot, since i just put this kit on and love to feel it work. I didn't spend the $3000 to drive slow!

edit: I forgot to mention that on long highway drives, I get about the same mileage or slightly worse than before turbo/FMU.

8:1 fmu and 310's untuned and i got 30+mpg highway, and 25-28mpg city. That's with a fair amount of boosting of course. Pretty much the same numbers I got stock

HOndata = 30 MPG or so easy.
Consider it, its the best.

Hands down.

i've also noticed that my mileage has gotten worse after turbo. even when i dont boost i can see my gas going down quickly. (shouldn't mileage be the same as if i were NA at this point) im only using an inline fuel pump and a fmu. am i really running that rich?

believe it or not... a MSD digital 6+ improved my gas mileage. youre running rich... what do you expect? lean it out if you can... but i recommend tuning to do it right.
