If I was getting that kind of mileage I would certainly not have any concerns, I would be quite happy. Its definitely not my driving habits, I pretty much stay out of boost unless I need to pass someone. Im a firefighter/medic and have had a perfect driving record for nearly 16 years, I am not some idiot kid who boosty boosts beetween every stoplight and such. I never do more than 5 mph over the speed limit as I cannot get tickets in my line of work.
Im hoping its an 02 sensor or something that is throwing the mileage off, Im just gonna go ahead and suck it up and buy new front and rear ones and download the datalogging program so I can send in my results for someone to review.
