same here. i'm running 285s and have noticed an increase off the line and in midrange as well. it's supposed to be great for towing too
as for a gas mileage increase, haven't noticed it yet. then again, it's so damn cold every day, i'm warming my car up for 10 minutes before I leave for work, so my mileage has been off anyway. theoretically, it should increase mileage though. the engine doesn't have to work as hard in order to achieve whatever speed you're going
