Hello team. After remapping, my engine started to vibrate on full throttle, i think the problem is bad start of injection, because i didn't touch it. How much it must be advanced to inject 51mg fuel fine? Also i attached file. can someone check it? Thanks :)

1) injectors
2) carbon on suction valve stems
3) other damage
4) anti-vibration control loop is somehow violated, see Bosch manual.
5) cylinders have uneven compression, damage to liners or colant leak and corrosion, etc.
