i have the ''Italian box'' from eBay
all i know is it makes the ECU think the rail pressure is low, therefore the ECU tells the high pressure pump to up the pressure, or something along them lines.
only problem im having is that my engine stalls really easily. whether hot or cold it constantly stalls!
apart from that, you can feel the difference in the engine, feels much more lively in the higher rev range when without the box it starts to die.
iv disconnected the box now as it is p***ing the fuel away and staling.
saving my pennies for a remap and DPF removal now
