I am pretty sure this change alone will bring you the last ml of fuel you want to get ! ( again not saying 11.5 @ 6500 is need with your SC cams under 1b ) ....
However, if you have some tools (pressure gauge etc) in your hands, you could do some investigation prior to buy it. At least you could check your usual "static" fuel system pressure. If still @ 6.8 or 7 b , you can try to add a single washer to the fuel pressure regulator, rise about 7.6b in static and see what happen.
By the way, are your injectors new or professionnaly cleaned recently ? if not, this is a "must do" prior to do anything else ! If your injectors are not flowing correctly, the entire range of RPM , fuel saving and even the reliability of the engine are compromised.
