Thanks, I think. 340 is the norm; 50mi commute per day with some (10~20%) stop n' go, plus cruising on the weekend. The 378 was on the trip to CA last summer. I had the stock chip at the time so probably would have done a bit more now with the Wong chip.

I don't think of myself as a mellow driver, but I guess I am as I have 15k miles on the current Sumi's and they're still going strong.

Really?! 150mi per tank-full?

I've always wondered what the MPG would be on the track, still haven't taken my car out yet to play, err REALLY play.
