Factory standard, it has a Bosch fuel injection system with 285cc 0 280 150 802 injectors (2.4 Ohm impendance, but there is a resistor pack), and the documentation states a max fuel rail pressure of 2.5 bar, less at idle. Max mid range boost i 0.560 bar and at 5000 rpm it drops off to 0.440 bar boost. I have tightened up the wastegate to a max midrange boost of ~0.9bar and 0.8 bar at 5000 rpm. In the last 25,000km or so this has not caused any problems, even though I have no idea how it's possible as 285cc injectors at 2.5 bar in a 2500cc engine at +0.440 bar should only just be able to service the factory 167hp. At 0.8 bar the Hp should be in the region of 200, which would seem to indicate something like a 97% duty cycle on the injectors. The turbo is a garrett T3 type.
