boosted car are all over the MAP on milage. I can get 20-21mph in my manaul hyper-miling on the freeway.

you can always get over what a manufacturer says if you drive to get milage.

I can get 11-13mpg lead footing aorund town with minor mods and I could get it down there stock as well.

there is no way I can maintain over 20mpg with many stop though. the only way I can get over that is speed down, slow starts, minimal stops.

I seem to get about 15mpg driving normal to my habits.

my Z06 was 24 freeway, 17 wooding on it and 20 driving how I drive. even at 7.0L which drank gas it was not quite as broad of range.
