I averaged 1 mpg more on this tank than I did the last tank (pre-tune), although I can't be sure the highway speeds/traffic ratio was comparable. Will report back after the next long road trip where I can directly compare highway mileage.
The power increase is more noticeable now, although it could just be due to the cool, damp conditions we've had lately. I'm actually surprised mileage didn't decrease this tank since the tune makes it hard to keep your foot off the throttle
