Fitting it was a doddle, took all of 15 seconds. I love it, the midrange throttle response is brilliant. When I fill up the projected distance per tank is shown as 685 miles, where it used to show 590. I've not yet used a full tank so I can't give you definite figures, but it does look encouraging. I have left the device set at factory settings (mark 5). Is there any downside to cranking it up to full power? I suppose the next question would be if there are any benefits to cranking it up?
