how to tell if injectors are maxing out?

In my datalog it shows the injector final pulse width in MSEC, is there a way to convert that to duty cycle?

It depends on how often they fire. If its SFI, then each injector fires once every two revolutions, so the total available time is 2 x (1/revs per second) x 1000 to get the total available time in msecs. Divide the pulsewidth by the total time and you have a DC.
