Still, I've been averaging 28 - 30 mpg this summer. Kinda abnormal, but I'm not driving "stop and go", either. Doesn't seem to make a difference whether I drive locally (semi-urban) or highway (sustained speeds of 75 mph).

I have verified the odometer with my old Garmin GPS72. Speedometer reading is optimistic at speed (by about 4%), but the odometer is accurate (monitored for 20 miles side by side).

This new SDL of mine has a stainless steel exhaust and a T3 Garrett running 18 psi of boost via a custom made controller (seems to lose top end power with any less). It never had a trap to begin with so everything is wide open.

I'm lovin' it.
