I have the flash tune along with the active tune and Graves EVR exhaust on My FZ10 and R1, I couldn't be more pleased, It made a huge difference on the FZ10, improving power and ride ability all across the RPM range.
Let me know if the gas mileage improves with the active tune hooked up. I got the EVR graves exhaust also and the 2wheeldynoworks upgraded flash tune. Im sure a dyno tune would be best, but the cost of it is almost the cost of the active tune controller?
