Gas Mileage after Programmer

[MVR 155]

We get an honest 12MPG with ours ( bounces between 11.9-12.2) with regular driving, most streets around here are 30-45MPH with a moderate amount of traffic lights. I do drive pretty easy, I figure its a big pig of a truck from a performance standpoint so there is really no need to be mashing the gas all of the time. I have yet to get any really decent mileage on the highway though, going 70-80MPH we have a really hard time seeing better than high 13's maybe 14, Overall Im pretty pleased with the mileage it gets.... not really much worse than any other big V8 SUV

I have a friend who also has an H2.... he has a set of 26" wheels and drives pretty aggresive and he is down in the 9-10 MPG range so depending on your driving style it can make a huge difference.
