I get around 300 per tank, more if I'm travelling. I usually fill up at about 280 and there's still a lot of gas in there (It'll take 18-19 gallons). My usual romps around town put me more in that 280 range. Best I've done is 330 all highway/travelling.

I have a PV catback and Hot Shots intake with no special tuning. Can't wait to see what the SC does to my mileage.
