It does seem to be a sticky wicket -- you need big injectors to work at WOT 
because there's very little time to deliver the fuel but big injectors 
deliver too much fuel at idle due to minimum pulse width. Could you keep the 
pulse width up at idle but compensate by dropping the fuel pressure?

Or, stated another way, you need big flow at WOT and little flow 
at idle.

If cost is not an issue, how about multiple small 
injectors per cylinder.  At idle, use only one 
injector.  

Unfortunately, adding injectors means all kinds of 
hardware modifications.
