roughly the same, I just upped my tire size a little bit so I am still wondering myself, the last tank had a ton of WOT runs on it cause I did alot of tunning this last weekend, but during the breakin 500 mile period I actually got 2-3 MPG more!!!!
Yeah.... My Wideband is a piece of crap, I am thinking of getting a new one....
