Installed injectors, cups and high pressure lines. Started right up and idled fine. Road tested the truck and could hear a tapping noise from driver's side. When I got to 50 mph the engine developed a really loud knock and started pouring white/grey smoke. Would number 4 being at this balance rate cause this? I'm leaning in that direction but am open for thoughts.

Eh possibly but that's not that high to cause all that. More than likely a cup leaking when that happens
