Good afternoon I stand in this forum with a humble question which would have to be the setting for the injectors to put my new Bosio pp520 dlc in a German Golf AGR completely standard engine with exhaust only totally free
I mean the injector if the subject of opening pressure (190bar) and closed (300bar)

regards

Raise the pilot pressures to 220bar, mains can remain 300 or be raised slightly.
You say "closed (300bar)", those are the main pressures, the pressures go much higher than 300bar.

Ok that clarifies much what I thought Thanks
