Default Mazda 6 High Pressure Fuel Pump

Hey everybody,
My mazda 2.2 diesel r2aa engine starts making strange things. Lost some power and hearing ticking noise at high rpm. I suspect fuel pump or fuel pump regulator. I can't find anywhere what fuel pressure should be in fuel rail at high rpm with full acceleration pedal pressed? Because now i have about 1500bars at 3000rpm.

You need to find a scan tool that show live data, both desired & actual fuel pressure.
