i would guess that more air means more gas. i only got above 30+ mpg during the break in period. at my first track event i got 8.6 mpg now that was a good time.
I have the same induction kit, and noticed a drop to circa 27mpg, however there was no change when I had the 200 bhp conversion !!!and I still return 27mpg plus .........
