    No way. 22mpg!!! I would kill for that kind of mileage. Does your iT have good acceleration? Mine is rather slow, especially coming out of a corner.

    I work in quality testing. I write test plans that are carried out by other testing agencies. Metrology is very complicated, isn't it?

    Default Well, it is a bit of a slug from a stop,

    but aren't all 525 autos? But, yeah, get the revs up a little bit and it's fine! Drop it into sport mode, with the chip, it's downright invigorating! If I'm on a highway trip, I get right around 28-29mpg. I think this is pretty standard for the 525's.

    Sounds to me like you've got one of those DOH things going on that when you find it you wonder how you ever missed it. Crappy mileage, no power... any chance you kinked a fuel line? Wrong filter? Or it could be a pretty severe vacumm leak. But this is out of my league. Take your advice from the experts here... they know who they are!
