gas mileage sucks! Can't seem to get beyond 14 around town, 17 on the highway and that's taking it really easy! I have an 06 V with Maggie, headers, stock exhaust, 8" harmonic balancer making 9 lbs boost and only 8000 miles. Spoke with Tom at Hendrix today, he believes it's "in the tune." I dynoed at 482 RWHP and 470 TQ several months ago. I repeatedly see posts with people claiming 20+ MPG and I've never even come close to this MPG. I measure by odometer, not the computer in the car. My air/fuel ratio shows a dotted red line just under 12 on the graph from the dyno, with the car almost perfectly following that line between 2-6.5. My tuner told me "that measurement is a tuner's dream," whatever that means. I gotta be missing something here!

I dont think your missing anything here. I know i was upset when people with cam, intake and headers were getting better MPG's than i was stock but they were still only around 16-17 city. I dont think any one gets 20+ city. The cam, headers and tune was getting them more power but in an efficient way. once you add forced induction you have no choice but to add fuel otherwise you'll run lean and thats no good. If i were you I'd be happy with 14MPGs city considering thats what i get stock.

I get 12/22. It's a joke. Been to my tuner several times complaining. He even threw a couple more degrees to see what would happen, so far nothing. I drive ~12 miles a day, it uses roughly $10 a day. It's getting old...

It could very well be the tune... I just had mine redone and I gained 4+ MPG on average... not to mention more power... I've got 112 blower, Walbro 255, Kooks 1 7/8", Corsa, Volant. I just took a trip to Cali and averaged 21.2 over the entire 900 miles with tons of enthusiastic driving...

It's a closed-loop tune, right? If so, I'd think part-throttle would be pretty much the same. I can't get to 17mpg in my daily commute, which is mixed driving/back roads. If your "city" is really like congested city, 14 might be as good as it gets.
