Hello Nadeem,
The exact calibration data is not freely available and was never made available to members of the public outside of Bosch repair shops.
However, from time to time literature from Bosch pops up on fleabay.
Unless you have access to and experience to use the specialized equipment necessary to properly calibrate the mechanical fuel injection pump, I would not recommend trying it yourself.
If you do not have access to the necessary equipment, then you can consider sending the fuel injection pump to Koller in Germany.
Have a look at their website:
