I was looking for the delays from Google one year ago. I have found only this link.

SIEMENS-DECA 006 injectors

2.5 bar 550ml/min
6 bar 860ml/min
Opening delay: 1.14ms at 14V
Closing delay: 0.85ms at 6 bar

Total delay would be 0.29 ms. 6 bar is quite high fuel pressure. Closing delay must depend of fuel pressure.
