My calculation was based on 60% WOT.

yep. not sure what magic the guy did with the tune on my Miata but I was getting mid to high 30's. I also had 3.6 rear end so that may or may not have helped.

Ha. At that point I had a 3.6 with a 6-speed and Aidan had a 3.9 with a 6-speed.

Miata with 260 whp also does about 8 mpg.

315 hp -> 260-270 whp on the Boxster?
