Re: what are you guys getting for mpg?

07 avalanche 5.3 4x4 flex with 104k miles. From the day I bought her brand new she never got over 15.5 mpg. I drive 40 city / 50 highway every day. Four weeks ago I decided to really watch my throttle input. No more WOT, nothing faster than 75, Easy acceleration! Mileage has gone up to 17.2! I am thinking of getting a bullydog gas tuner and maybe gain another 2-3 miles. I would be psyched if I could see 19-20!

Anybody running bullydog tuners? Anyone done any real fuel consumption comparisons?

Also thinking of new injectors and plugs since they are original!
