Defender vs Discovery Bosch Fuel Pump

Is there any difference in power output from a standard Defender 300tdi engine with Bosch Fuel Pump and a standard Discovery 300tdi Bosch Fuel Pump.

Im talking pumps at standard factory settings for the minute.

Been doing some research and from what I have read if you have a standard 300tdi Defender Bosch fuel pump but swapped to a Discovery Bosch fuel pump you could gain +3kw and if you fitted an even later Discovery EDC fuel pump the gains could be +10kw.

What about a Defender 200tdi pump and a Discovery 200tdi pump?

The edis fuel pump will need the computer fitting , as well as the immobiliser, and a TD5 speedo and speed transducer to operate correctly (or at all) . HTSH
