Fuel efficiency at higher speeds is mostly aerodynamics and gearing.
Rolling resistance (in W) grows proportional to speed, aerodynamic drag by cube.
That's also why I suggested picking a speed and sticking with it, as it's the most efficient way to archive a high average speed.
Pulse and glide also doesn't work above a certain speed as you're running your engine close to maximum efficiency regardless.
On a sidenote:
In an older Mercedes Benz E200D (2,2L turbodiesel, 6-speed manual, wagon) I archived peak fuel efficiency at 110 km/h or about 70 mph.
However these things somehow are very aerodynamic and geared ridiculously tall.
In my Spyder that's impossible to archive since I'm spinning over 3000 rpm at that point at a rather low load.
