I first hooked it up and only changed the tuning for regular fuel. With that I did not notice much. So I chnged each shift point to +500 and the rev limit up to 6500 along with the tuning for regular fuel, then I got a 30mph increase in the same distance from starting out and it looks like I'm getting better fuel economy as well from the mileage to gauge ratio. I won't be for sure until next fuel up but I really like this tool.
