Max fuel flow is related to the size of the head and lift of the cam plate. I would get rebuilt injectors and have them set at the high end of the spectrum of opening pressure, that should help with atomization. From there, you can go to a 11mm head. There are also higher lift cam plates, though you would need a new head to go with that anyway, as installing a higher lift plate once the head has already worn in would be bad. Also, for full potential of the pump, a lift pump should be installed. If you can find a diesel compatable pump over there that pushes around 15 psi you will be good. Much over 20 psi and the front shaft seal can start to leak or blow out.
