On a 650 mile highway trip last weekend from SF to Santa Barbara and back, I saw 23.5 MPG. Key differences between this trip and others are the Pilot Sport Cup 2 and the Revo 1+. In the past I’d see closer to 25.5 MPG. When I was stock I was closer to 27.5 MPG, and 30 was theoretically possible on long highway stretches at 80 MPH if you didn’t rip the throttle on onramps.
