2007 Touring with 80k miles. Installed the vcm muzzler lately and it improved fuel economy, go figure... At 70mph with the wife and 3 kids I get a constant 27.5-28 mpg on a 200 miles trip (Montreal to Quebec city) no difference either way. I used to get 24mpg before the vcm delete.
I did a test once driving the entire trip at 65 and I got 31 mpg, I'm really impressed with that. It's a different story when driving in the city though, almost doubles the fuel needed and I'm not hard on gas pedal.
