Big difference in power. I get 3 to 4 mpg more when using performance level.

Really a nice device. I am amazed at all you can monitor with it. My main reason for purchase was to monitor the transmission temps when towing my 17 ft travel trailer. But I'm also monitoring fuel mileage and throttle position. I only gave 4 stars because the included velcro for mounting allows for too much vibration. Replaced it with a 3M Command strip refill.
