Have your adjusted the throttle lever to get more travel?

The biggest difference is to install a 3200 RPM governor spring; it can be had from any injection shop, Bosch part number 1-464-650-366, for $20. Installation isn't too bad.
Advancing the timing will give you some better top-end in exchange for less of a bottom end.
Maxing the fuel screw to just south of runaway will give you more power across the spectrum.
Making sure that you're getting full throttle travel is a really good idea, as is turning the high-idle adjustment screw plush to the case.
Another thing that is supposed to really help it move out at speed is a bigger compressor housing. HTT sells a couple compressors that flow a lot more air at speed.
