Is the mechanical condition OK? No air leaks, compression good, clean/new plugs, injector spray pattern tested.

Is it wired correctly? lower / upper injectors aren't swapped or something, injectors / coils wired in firing order not cylinder number.

Do you have any diagnostics errors on ref/sync, injectors or ignition?

Do all sensors values seem reasonable?
