Dont be so angry. This is how the forum work, to get more informations. Like I wrote, I'am not expert on diesel.
I do what I can do in mechanical things, and I know how combustion chamber work. I see that You wrote there is different spray angle (that's the reason I ask to change nozzle). I want to find best solution for me.
Also I don't want to remap my car, I leave this to pro beacuse I don't have proper equipment to to this. I just want to do mechnical things and give car to remap.
Ok, so please tell me another thing because I heard different opinions... If You give injector to "repair" and calibrate, is true there are no in production new "relay/coil" in injector ?
