Consistency across all injectors is also important, not the same engine but OM606 n/a and turbo have different pop pressures for US and Euro. Here, they are both set to 115 bar as stamped, but US one is 135 bar (can't remember which way around).

I always advance the timing on these engines which makes them far more responsive and less soft under pedal.
