Thank you for all your answers. I think I am thinking too much in a purely mechanical way like my old AX is (being a newbie with recent cars), where injected quantity is almost only dependent on accelerator position, by cable by the way.
In the 307, injectors are electronically controlled, there are sensors everywhere... As you said, something is happening somewhere in that 1500/2000 rpm range and the ECU is commanding injection with respect to the pre-programmed map and sensor information.
I will try to investigate with more tests focused on that rpm range.

Don't know. Is that only for petrol engine or diesel as well ?
